Pipeline failed without any trace

Hi All,

We have recently started using Gitlab-CI by replacing old CI system. We run Gitlab-CI for Ruby projects.
Sometimes commit authors are receiving pipeline failure emails.
All jobs in Pipeline are failing with No Job Trace. Also unable to find any information in Runner logs.

Can anyone help on it?

Thanks in Advance.

Is your .gitlab-ci.yml valid? To check you can navigate to the file in your repository in the browser app. If it is faulty, it will tell you above the source code, also mentioning why.

Same issue for us, new pipelines fail without an error trace since earlier today.
What is going on ?
