"This pull request is broken due to missing fork information." after pushing

[lenianiva]

Description

I have been using Gitea 1.20.2 for over a year now and recently I started to get "This pull request is broken due to missing fork information" on my pull requests. I can still interact with my repositories in the normal way

I then updated Gitea to 1.21.11 and the issue persisted. I have tried going to the dashboard and:

• Update the '.ssh/authorized_keys' file with Gitea SSH keys.
• Update the '.ssh/authorized_principals' file with Gitea SSH principals.
• Resynchronize pre-receive, update and post-receive hooks of all repositories.

The hooks from a repository suffering this issue are:

$ ls hooks
applypatch-msg.sample	   post-receive.d	  pre-merge-commit.sample    pre-receive	 proc-receive.d		    update.d
commit-msg.sample	   post-update.sample	  prepare-commit-msg.sample  pre-receive.d	 push-to-checkout.sample    update.sample
fsmonitor-watchman.sample  pre-applypatch.sample  pre-push.sample	     pre-receive.sample  sendemail-validate.sample
post-receive		   pre-commit.sample	  pre-rebase.sample	     proc-receive	 update

Gitea Version

1.21.11

Can you reproduce the bug on the Gitea demo site?

No

Log Gist

No logs are generated for gitea/log and log in the gitea directory, so I'm not sure what log to include
