RNFetchBlob.ls got 1 arguments, expected 2 invoke

MAY BE A BUG

When I am trying to get all files from sccard directory, it throws an exception.

I am testing on android, samsung TAB A. Has anyone the problem like this.

thanks in advance :)

code snipet:

RNFetchBlob.fs.ls(PATH_TO_DIRECTORY).then(async files => {
                    alert(files.length);
                }).catch(error => {
                    alert(error);
                });

Does this only happen on Android? It might be that your application doesn't have the external read/write permissions either in the manifest, or if your Samsung TAB is running Android 6.0+, it isn't asking for storage permissions at runtime.

If you can post the exception you are seeing, it might help to narrow down the problem.

@tombailey thank you for your response. I defined every persmissions, in manifest file. Interesting thing is that, it works with old "react-native-fetch-blob" but not works with "rn-fetch-blob"

import RNFetchBlob from 'rn-fetch-blob'; // Not works with this library
import RNFetchBlobOld from 'react-native-fetch-blob'; // Works correctly

RNFetchBlobOld.fs.ls(PATH).then(files => {
  // Works
});

RNFetchBlob.fs.ls(PATH).then(files => {
  // Not works
});

Here is the exception:

RNFetchBlob.ls got 1 arguments, expected 2

Can you tell us the versions of react-native as well as the versions of react native fetch blob that you are using? (both the old version and new version)

Looking back at the original react-native-fetch-blob repo it seems to require a callback parameter, so I'm not quite sure how using the old fetch blob is not failing when you aren't passing in a callback

[baxri]

I am using following versions:

{
   "react-native": "0.55.3",
   "react-native-fetch-blob": "^0.10.8",
   "rn-fetch-blob": "^0.10.11"
}

facing same issue.

[xhw1993]

same issue, is it a bug of new version at 0.10.13 ？ because I find it is correct of old version at 0.10.8

[tombailey]

I believe we need to annote the native static function with "@reactmethod". I can't do this right now but will try later.

This:

static void ls(String path, Promise promise) {
//...
}

Should become this:

@ReactMethod
static void ls(String path, Promise promise) {
//...
}

Any update on this issue, running into something similiar.

RNFetchBlob.mkdir was called with 1 arguments but expects 2 arguments.

@xhw1993 this appears to be fixed as of 0.10.13

@rollsroyc3 same issue here, did you ever find a solution?

[tombailey]

@CurrieBen can you ask them to update their fetchblob version to 0.10.13? I tested this back in October and it seemed to be okay on 0.10.13

This is still an issue. Native library expects a callback (which is largely unused), which this library does not provide, thus causing this error. You can patch this yourself in node_modules by adding an empty callback function.

If anyone is using redux-persist-filesystem-storage, they need to pin their version to 1.2.0 (ie. "redux-persist-filesystem-storage": "1.2.0" (removing the ^ in front of the version n umber), otherwise they'll get this fork instead, which is actually broken.
