I have an instance of Upsource (2018.2.1154) integrated with self-hosted GitLab and auth plugin enabled. Commits, comments, merge requests and branches synchronize properly, but file contents are somehow forbidden from being shown.
Displayed error is: /git4/Test2.java: file was not imported, forbidden by project settings.
In error logs there is stacktrace caused by com.jetbrains.upsource.backend.server.core.db.ContentMissingException with the same message
Upsource connects through my account's private ssh key to my own repository.
GitLab project has public visibility and everyone with access can see anything (Issues, Repository, MR, forks, wiki, snippets):
I've clicked through subjectively all project settings in both services, but I couldn't find anything that would look like one restricting such import. Searches don't show anything about this error.
