fatal: bad default revision 'HEAD'

I installed redmine_git_remote and checkout a remote repository in redmine. Then, I visited the /projects/my_project_name/repository page and got the "Internal Error" page. I checked the path of the local repositories and saw the project's files there. I try another 2 repositories and they all work well. The error log of redmine shows:
