It seems that there is an invalid submodule in the repo.

And it is a bug on Gitea side, it shouldn't panic ...

-> Fix submodule nil check #35096

[wxiaoguang]

As a workaround, you can also downgrade to 1.24.2 temporarily

[wxiaoguang]

The fix for 1.24 is ready in nightly build:

• https://dl.gitea.com/gitea/1.24-nightly/
• https://hub.docker.com/r/gitea/gitea/tags?name=1.24-nightly

[urz-hgw]

Thanks for the fix @wxiaoguang, I just tested the nightly build but there is still some issues.

In my case a user has a repository with folders as submodules, but the source does not exist anymore (404).

Gitea v1.24.2 shows the full repository with all files/folders and submodule commit id.

Gitea v1.24.3 throws a 500 and does not show anything at all

Gitea v1.24-nightly throws a 500 but shows every folder/file until the submodule folder, the submodule commit id link is not shown and the rest of the output is broken.

The log says:
