[Bug]: Fallback false is ignored

[j0nezz]

Summary

Netlify triggers a new ODB function instead of returning the expected 404 when using fallback: false.

See: https://github.com/netlify/netlify-plugin-nextjs/blob/6fd7bcc99aacf447559de46f60de6d8cb33e7a59/src/helpers/utils.ts#L80-L88

Context:
We have a top level dynamic route, so that we can create new landing pages directly from our CMS. Because fallback: false was ignored, every request to myWebsite.com/:uid resulted in a new ODB function being triggered. However, these requests were for example also triggered by crawlers requesting robots.txt (which was missing at that time). Another edge case leading to a huge number of function invocations was the usage of the nextjs Link component for a route with a configured redirect (in _redirects). Because Nextjs prefetches routes, it tried to prefetch the JSON of the route (which didn't exist because it's a redirect). This would not have been a problem (only a failed request in the network tab of the browser, and it can be fixed by disabling the prefetching)...However, with Netlify ignoring fallback: false, a new ODB function was spawned for every prefetch request (which could be many per user session).

All in all we accumulated 170k+ function invocations in one weekend. I know that the above described scenario is very specific (and could have been avoided) but I wanted to emphasize, that the i18n fix can result in some unpleasent surprises for Netlify customers that use fallback: false and expect it to work as described in the nextjs docs.

We also have multiple builds that are affected by this bug. We have a dynamic route which creates pages based off the slug provided by our CMS. The defect was noticed in production when visiting any route not available in the CMS, which should return a 404, however we are seeing 500 - internal server error. The appearance of the bug seems to coincide with recent version changes, we were able to confirm that by upgrading a previously unaffected site from v3.9.2 to v4.2.3, which introduced the 500 errors. We confirmed that it is being sent to the netlify-odb-handler. We are investigating further now, please let us know if any additional details are needed.

@BenMcGrath1 Function logs would be very useful, thanks

[BenMcGrath1]

Below is the function log for the odb-handler. Its worth noting we believe the error is happening upstream of the odb-handler function, possibly here: https://github.com/netlify/netlify-plugin-nextjs/blob/6fd7bcc99aacf447559de46f60de6d8cb33e7a59/src/helpers/redirects.ts#L68

Hey @ascorbic,

I'm having some trouble serving a deploy preview locally or to netlify with the suspected problem line commented out in the build plugin to verify this, but I suspect the problem redirects that are being generated in our case relate to our dynamic route template at /pages/[...slug].js. Here's an example of the generated redirects from the deploy log:

6:20:01 PM:     from: '/_next/data/build/:slug/*',
6:20:01 PM:     to: '/.netlify/builders/___netlify-odb-handler',
6:20:01 PM:     status: 200,
6:20:01 PM:     force: false
6:20:01 PM:   },
6:20:01 PM:   {
6:20:01 PM:     from: '/:slug/*',
6:20:01 PM:     to: '/.netlify/builders/___netlify-odb-handler',
6:20:01 PM:     status: 200,
6:20:01 PM:     force: false
6:20:01 PM:   },

The template in question uses getStaticProps without revalidate and getStaticPaths with fallback: false (doesn't take advantage of ISR/SSR). netlify-plugin-nextjs appears to be generating redirects for any prerendered dynamic routes and their related data routes that don't match middleware at line 201 in the redirects.ts file. I must be missing something, however, because that would mean that all prerendered pages, regardless of their fallback status, are being referred to the odb-handler rather than being served from the deploy build cache in cases where the page has already been rendered. A dynamic route is not necessarily an SSR route or an ISR route, but this appears to treat it as such.

[ascorbic]

Hi @hu0p
Pages pre-rendered at build time will take priority over those rewrites (hance force= false), so the ODB handler will only be hit for pages that haven't been rendered. Other pages will hit the handler the first time they are visited, but that response will be then cached until the next deploy. As the comment states though, for reasons that aren't entirely clear to me, Next.js doesn't always pre-render static paths for other locales, and instead serves them dynamically. For this reason we need to hit the origin to be certain it's a 404. I will need to look into possible workarounds for this though, as I understand the problem of not wanting to accumulate these invocations.

Ah, got it. I overlooked that force: false bit when I was familiarizing myself with the repo and control flow inside redirects.ts. I totally forgot about that option. Thanks for pointing that out! This makes perfect sense.

I will need to look into possible workarounds for this though, as I understand the problem of not wanting to accumulate these invocations.

Thanks for recognizing our concerns. That's a big part of it, but it also leads to negative SEO consequences. 500 errors are logged in GSC as errors that can cause routes to be prematurely dropped from results before they can be caught and redirected by content managers. The current behavior also really doesn't align with the Next.js API as documented. I apologize if it sounds like I'm beating a dead horse. I promise that's not my intention. Rather, I just wanted to share these thoughts so they can be taken into consideration when working towards coming up with the workaround you mentioned.

Perhaps in the meantime a solution would be to manually force a 404 when page data is unavailable? I don't love it because this is not the originally intended use case for this functionality and it otherwise wouldn't be necessary in any other environment, but it could at least address the problem for us (and anyone else who stumbles across this) in the meantime. It might make sense to include a note about this somewhere in the docs as well if you're open to it.

We're actually working on a large i18n project at the moment, so this is also relevant to us. Just out of curiosity, when you were testing this, were the locales configured in next.config.js and being passed as a property for each individual path that is desired to be prerendered in the paths array in getStaticPaths as shown in the example here? That is a bit of an edge case for the fallback property that sounds like it could apply here.

This is clearly a bug. It should be returning a proper 404 page. Do you have the function log for one of those requests?

[hu0p]

Are you sure? The test case here would be visiting a route that doesn't and wouldn't exist, so something like /asdfasdfasdf. This route isn't listed in the paths array returned from getStaticPaths, so it isn't prerendered. However, it does match the [...slug] dynamic route in the manifest, so it gets passed to the ODB handler and hits the origin as you noted, which triggers the following behavior defined in getStaticProps (simplified a bit here):

export async function getStaticProps({ params }) {
  const slug = params.slug?.join("/")

  const { data } = await getPage(slug)

  return {
    props: {
      key: data?.id ?? null,
      content: data?.content ?? null,
    },
  }
}

You can actually see an example of the function logs in Ben's comment above (we represent the same organization). I'm afraid there's not much interesting going on there. It's just a 404 response from the CMS (Storyblok). Axios or the CMS SDK inside the getPage call may be throwing an exception or it could be an error during page generation triggering the client-side error. Either way it shouldn't hit the handler at all and should 404, right? There is another site that doesn't use the SDK that we believe is also affected by this, but it has slightly different behavior. Same plugin version and test route (more or less), but it just generates an empty page (200 status) and doesn't make a json request for the page data. My guess is it's just a difference in rendering (null check on the client). These should 404 too.

The logs for that site are pretty interesting though. Those requests come through without error to the ODB handler, but they also include requests for page data that should be pre-rendered e.g. contact, about, careers:

I tried manually returning a 404 inside getStaticProps like I mentioned as a workaround before, and I can confirm that works. However, it still triggers an unnecessary invocation, of course.

Something else I noticed: an empty /_next/data/build folder is generated at the top level of the directory when I use netlify-cli to run ntl dev --live or ntl build locally with the plugin (cloned repo, file based configuration in netlify.toml). Do you have a typical workflow for this plugin? I've cloned it into an existing site, configured it in netlify.toml, and run npm run watch to generate the lib folder, but any time I attempt to do test deploys I experience some odd broken behavior that I don't get in production. Any idea what I could be missing?

Sorry, to be clear I meant it's a bug in the plugin not in your code. I'm going to deal with some other fixes today and then see if I can look into this. Can you confirm whether you're using i18n in this site? If possible, could you share your .next/prerender-manifest.json file?

For CLI deploys, you need to run netlify deploy --build, rather than building and deploying separately.

So good news! The pages I noted above that should be pre-rendered were not due to a bug in the plugin. We overlooked a hidden default per_page count/limit in the CMS API. The only issue we're definitely dealing with here is the improper accumulation of invocations for pages that should 404 which match a given dynamicRoute in the .next/prerender-manifest.json. Sorry for any confusion this may have caused, and let me know if we need to move this to a new issue.

For CLI deploys, you need to run netlify deploy --build, rather than building and deploying separately.

This must be a separate bug. I tried this at one point (and just now) and was able to reproduce the error we're discussing, but I kept getting 500 errors from the _ipx function which caused all of the images to break.

Can you confirm whether you're using i18n in this site?

Neither of the sites I mentioned are using i18n.

If possible, could you share your .next/prerender-manifest.json file?

Yup, see below for the site that matches the ODB logs I shared above. This is the site that was giving us 200 statuses and empty pages in places where it should 404. The page/pageData being erroneously fetched are handled by

...
  "dynamicRoutes": {
    ...
    "/[...slug]": {
      "routeRegex": "^/(.+?)(?:/)?$",
      "dataRoute": "/_next/data/build/[...slug].json",
      "fallback": false,
      "dataRouteRegex": "^/_next/data/build/(.+?)\\.json$"
    },
    ...
  }
...

Here's the full manifest. Ignore the fact that it doesn't include the real looking pages from the ODB logs above. I pulled this before I found and fixed our bug

Hey was going to make a new issue but I think it's the same.

When visiting a dynamic route that should return a 404, there is an attempt to render server side.
https://abtest-middleware.netlify.app/dynamic-routes/this-should-go-to-404

I thought this could be something to do with middleware but also appears to happen on non mw pages
https://abtest-middleware.netlify.app/dynamic-routes-no-middleware/this-should-go-to-404

Link to repo

Function log of ___netlify-handler

Nothing from ODB

If you need any further info let me know!

Also can we try keep massive logs inside a <details> tag 😎

Good idea. Updated!

Sorry for bumping the thread but just wondering if a fix for this bug is in the pipeline?
Or maybe I have missed something and this isnt a bug at all 🤔
