I have set up my pipelines on Azure DevOps such that pipeline_A would trigger pipeline_B after successful completion. The yaml file for pipeline_B looks like this:
trigger: none
resources:
pipelines:
- pipeline: create_function
source: pipeline_A
trigger: true
where pipeline_A is the name of the triggering pipeline as it appears in the "Pipelines" section.
I am running pipelines on the master branch, and have set the default branch for triggers to master. However, pipeline_B never gets triggered after pipeline_A finishes.
I had tried the same functionality on another pipeline on a test branch a few weeks ago and it was working. So, I'm not sure what has changed since then.
