Build notification to slack channel is not working
Hello,
I'm using Gitlab CE 8.14.5. I've enabled the Slack service for several projects following the documentation (link below). The slack service was enabled for "Build" events. I didn't enable "Notify only broken builds" option as I wanted every notifications. But, it's not working for me.
From Settings UI, if I click on the "Test Settings" button, then I get a message in the slack channel. But, when a build on the master branch is completed, I'm not getting any notification on my slack channel. I recall this was working fine before upgraded to 8.14.5. Not sure if this is a bug or not. Have I missed any configurations? Why does it only work when I click on the "Test Settings" button?
