RNFS.readDir() error Attempt to get length of null array

Reference to https://github.com/itinance/react-native-fs/issues/462

I followed the above issue solution, still got the same error:

the code:

const granted = await PermissionsAndroid.request( PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE, ); if (granted === PermissionsAndroid.RESULTS.GRANTED) { console.log('onPressDownloads write granted...'); try { let files = RNFS.readDir(RNFS.DownloadDirectoryPath); console.log("onPressDownloads files: ", files); } catch (error) { console.log("onPressDownloads error: ", error); } }

I am using React-native info: "react-native-fs": "^2.16.6",

I have the use permissions in AndroidManifest.xml file:

and under <application tag, I have android:sharedUserId="android.uid.system"

I can read other folders like RNFS.DocumentDirectoryPath, but for folder RNFS.DownloadDirectoryPath, I got this error:

ExceptionsManager.js:126 Unhandled promise rejection Error: Attempt to get length of null array at fn (NativeModules.js:99) at readDirGeneric (FS.common.js:181) at Object.readDir (FS.common.js:253) at Object._callee5$ (index.js:453) at tryCatch (runtime.js:63) at Generator.invoke [as _invoke] (runtime.js:293) at Generator.next (runtime.js:118) at tryCatch (runtime.js:63) at invoke (runtime.js:154) at runtime.js:164

Please help!!

Thanks

I faced the same issue

Same error, is there any solution for that?

Same error, is there any solution for that?

Did you try this?

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

any updates on this ?

relate to Android FileProvider?

Same code, work on android 7.x, same error on 11.x

Occurred the same problem on Android when I tried to backup data files through ADB shell, although I chmod/chown these file's privilege, not fix...
