Error message while deleting file or folder

[DecaTec]

Describe the bug NC instance with app recognize installed. When deleting fole or folders, an error message "Error while deleting file " is shown and die file/folder seems to be still present. But when refreshing the page, die file/folder was actually deleted.

Here's the log entry created while deleting file/folder:

[webdav] Fatal: Error: Call to undefined method OCP\Files\Events\Node\NodeDeletedEvent::getSubject() at <<closure>>

Same issue, deleting any image results in a 500 internal server error, response below

Hello, I also have this concern, I had made the request on Nextcloud before realizing that it was related to this application!

[samdeeshmenia]

I also faced the same, solved after recognize was disabled

Thank you for reporting this! I'm aware of the issue but am focusing on getting v3 ready for a release, which will also fix this issue. Stay tuned :hearts:

[usernamehyphen]

this is a showstopper for me personally, deleting when syncing my disk with my nextcloud instances is somewhat more important feature than having face recognition. you can merely add the method with pass in it and thus bypassing the server error when trying to invoke nonexisting function, no? please fix it, i still would like to have recognize enabled eventually.

I sadly don't have time to maintain Recognize v2. I recommend to deactivate it until you are able to upgrade to v3 (which only supports Nextcloud v25). Thank you for your contributions!
