This file was not found or is no longer available
Report abuse API returned reportAbuse.fileNotFound when the referenced file does not exist or is gone.
Why this happens
Stale file id, already purged, or private/unavailable file. UI alert may show the longer invalid-link message instead.
Diagnose and fix
1. Open Report abuse from the file's download page if it still exists.
2. Or describe URL/filename in the message without a linked id.
3. See Report abuse (member).
4. See validation articles if email/reason/body fail next.
