I am currently developing an app based on a file provider extension and intermittently encounter the error: No valid file provider found with identifier.

Usually, I can mount (addDomain) successfully after building the app, but occasionally this error appears and then disappears after 10-15 minutes

I see these errors from log stream:

When the issue occurs, the following command does not list my provider:

fileproviderctl dump

Any help would be greatly appreciated. Thanks!

Hi, I always meet this error! Unfortunately the Apple dox skip the point about setting the various .entitlements / .plist files settings so I’m completely lost about. I don’t post here because as usual this forum is deserted by everybody, Apple engineers first!

If you have any clue or you solved the issue pls let me know; I’ll write a post on my blog for future reference if somebody else needs help.
