Description

Steps:

Run these commands to set up your repository:

git init --object-format=sha256
touch test
git add .
git commit -m 'Initial commit'

Push it to a gitea instance.

Results in fatal server-side error:

$ git push -vvv origin main
Pushing to codeberg.org:h3xx/test-sha256
fatal: protocol error: unexpected capabilities^{}
fatal: the remote end hung up unexpectedly
Gitea: Internal error

Note: that's literal ^{} garbage characters.

Expected:

A better error message. This one makes me feel like I broke your site.
OR (and I realize it's a long shot) support for SHA-256 object hashes
