Sorry @jeyasuriya1994,
This is part of the same issue with https://community.datocms.com/t/build-trigger-not-detecting-gitlab-pipeline-status-if-we-stopped-manually/7713/4, I think, and the developers have been informed.
We also got your email about the same issues and will respond as soon as we have some findings. In the meantime, we recommend setting up a custom build hook that you can configure to your liking (details in our email response), just as a temporary workaround.
We’ll write back once we have more info. Thanks!
