Pushing many commits with 'Require Signed Commits' enabled fails with 'Gitea: Internal Server Connection Error'

[Mik4sa]

Description

On a private repo / gitea instance I merged our default branch into a fairly old feature branch resulting into 1938 commits to be pushed at once. When pushing I get an error after about 64 seconds, so roughly after a minute.
This is what I get in my console:

$ git push

 ! [remote rejected]       test-push-many-commits -> test-push-many-commits (pre-receive hook declined)
error: failed to push some refs to 'https://gitea.[...].de/[OWNER]/[REPO]'

In the logs from gitea I've found these messages:

2024/11/28 09:44:43 ...hook_verification.go:50:func2() [E] readAndVerifyCommitsFromShaReader failed: Unverified commit: 5e282dc2d42e2376b183e2f8fb432e0eff9769a3

I tried the push several times, so I found this error for every try:

Note that branch protection for this branch (all branches) is enabled. The only enabled setting is 'Require Signed Commits'.

The log states that there are unverified commits. Which isnt true. Looking into the default branch I can see that the commit is signed and verified by Gitea. All of them. Interestingly it's always a different commit which should be unverified, according to the logs. Also this error always appear after 61 seconds which is very close to 60 seconds. Sounds like a timeout or something.
The push was successful after I disabled the requirement for signed commits.

Is there a timeout for the pre_receive hook I can adjust or for the signature check? I couldn't find any.
Also I tried to quickly check the source code but couldn't find any timeout, directly. But note that I'm not firm with go nor with the code of Gitea.
