getResourceFromContext returns null when using sparse fieldset for resource type

[shadcn]

const node = await getResourceFromContext("node--article", {
  params: {
    "fields[node--article]": "title"
  }
})

The code above (on a Drupal site with translation enabled) will return null because of the bug here:

next-drupal/packages/next-drupal/src/get-resource.ts

Lines 59 to 67 in 4022f62

	// If no locale is passed, skip entity if not default_langcode.
	// This happens because decoupled_router will still translate the path
	// to a resource.
	// TODO: Figure out if we want this behavior.
	// For now this causes a bug where a non-i18n sites builds (ISR) pages for
	// localized pages.
	if (!context.locale && !resource?.default_langcode) {
	return null
	}

Solution: Always include default_langcode for the resource (until this is resolved in decoupled_router).

const node = await getResourceFromContext("node--article", {
  params: {
    "fields[node--article]": "title,default_langcode"
  }
})
