Gitlab commit failed pipeline

I have committed and pushed the code to git and get following mail immediately after the commit.Attached is the screenshot of the same.

.It has failed pipeline with 0 failed jobs.
What does this mean and how to rectify this?

If you click on the Pipeline ID do you get more information? This could happen if your YAML config (.gitlab-ci.yml) is not well-formed, for example. You can check that with the CI lint.
