500 Error on Saving Settings

Hi community,

I’ve run into a snag with my locally hosted version of GitLab 10.0.0-rc2. In one of my projects, I am unable to change the CI/CD timeout. In fact, I can’t save any of the CI/CD settings. Other settings save fine, and other projects save this one setting fine as well.

Steps to reproduce

  1. Go to project
  2. Go to Settings -> CI/CD -> General pipelines settings
  3. Hit Save

Output

I see traces of problem in the log, but am not familiar enough with GitLab nor Ruby to pin it down.

What could I do to try and narrow this down further? I’m tempted to start a new project and potentially import this one into it to see if that fixes it…
