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!

When capturing materialized information from materializedItemsDidChange in NSFileProviderReplicatedExtension, the isDownloaded property of NSFileProviderItem is not set during the call to enumerate items (NSFileProviderEnumerationObserver:enumerateItems(for:startingAt:)).
Both the IsDownloaded and isMostRecentVersionDownloaded properties are returning false, even though the item is fully materialized
How to capture this information from file provider extension ?
Any help would be greatly appreciated. Thanks!
How can I read a dataless file from within the same or another FileProvider extension?
When I pass the visible URL to AVAsset from AVFoundation, it throws the following error:
Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSUnderlyingError=0x15b01b1e0 {Error Domain=NSPOSIXErrorDomain Code=11 "Resource deadlock avoided"}, NSLocalizedFailureReason=An unknown error occurred (11), AVErrorFailedDependenciesKey=(
"assetProperty_Tracks"
), NSURL=file:///Users/<<username>>/Library/CloudStorage/<<file-path>>, NSLocalizedDescription=The operation could not be completed}
The code snippet works fine if executed as a separate Swift process.
I'm using AVAsset with AVAssetExportSession to export a subset of the file being read. So I can't use NSFileProviderManager.requestDownloadForItem(withIdentifier:, requestedRange:) because I don't know the offset range required by the AVFoundation library.
