ListCorpusWorkerVersions and RetrieveWorkerVersion should use IsVerifiedOrReadOnly
The frontend calls ListCorpusWorkerVersions as soon as a corpus is selected in the navigation to display the worker version filter in element lists. It also calls RetrieveWorkerVersion even when the worker version is already in the store to display a particular worker version linked to an element/transcription/etc.
When logged out, this causes a 403 because these endpoints use IsVerified
. We could avoid the call, but that would bean removing the worker version info and filters from all over the frontend when not logged in.
