"Not a valid object name main" error about wiki

Hi,

Each time I go to a project webpage, Gitaly throw a "Not a valid object name main" error log message.

If I create a wiki page, then I do not have anymore this error.

I suppose that checking that the /repositories/@hashed/d4/73/d4735e3a265e16eee03f59718b9b5d03019c07d8b6c51f90da3a666eec13ab35.wiki.git directory exists before running git will avoid that situation.

I have seen this log on GitLab FOSS 15.11.2, 16.1.0 and 16.2.1 (installed from sources).

Best, Adrien
