Getting 500 internal server error when search within the project

Hi All,

I am new to Gitlab. We are getting 500 internal server error when we search anything in a specific repository. But search is working from the Dashboard.

We are using GitLab 7.13.2.

I am expecting your valuable troubleshooting tips

Dear community,

I am facing exactly same issue (GitLab CE 8.6.5).

I can find following related error message at production.log file:

Completed 500 Internal Server Error in 895ms (ActiveRecord: 20.2ms)

ActionView::Template::Error (wrong argument type nil (expected Regexp)):
    1: - blob = @project.repository.parse_search_result(blob)
    2: .blob-result
    3:   .file-holder
    4:     .file-title

Any help would be appreciated.

Thank you,
