PlatformDispatcher.instance.onError: PathAccessException: Creation failed

[vtisnado]

Hi guys,

I'm getting the following error and I can't find how to fix it. In Android the cache it's not working, but on iOS breaks completely the app. Any clue what can be wrong?

PathAccessException: Creation failed, path = '/var/mobile/Containers/Data/Application/6CB0330F-A495-58C4-493A' (OS Error: Operation not permitted, errno = 1)
flutter:

Is anyone else facing this issue?

The exception is pretty clear to me, your app has no access/permission to the directory you set up.

The exception is pretty clear to me, your app has no access/permission to the directory you set up.

I thought exactly the same and tried to add more permissions to the app, but didn't worked.

Couple things to take in mind:

1. App was using Hive without any special permission. The error start happening after an update I made after the release with this library.
2. The app works fine when I remove dio_cache_interceptor.
3. Yo mentioned that the app "has no access/permission", could you share any documentation about this? I could not find any working solution in the pub.dev page, Github or Stackoverflow.

I deeply appreciate if you could guide me, since I have weeks trying without luck.

If you already are using Hive in your app, set the directory parameter to null. This will avoid to call internally Hive.init. This may be the cause of the issue then.

Thank you @llfbandit ! This fixed the issue in Android and iOS! I would never figure it out.
