Hi Raj D,
Thank you for posting query in Microsoft Q&A Platform.
Triggers will only run on LIVE mode. That means, only published pipelines (to Live mode) can be executed from triggers. For this trigger also should be published.
for some reason you want to execute pipelines with unpublished changed then we should go with debug execution only.
Hope this helps. If not, kindly share little more details on ask with simple example if possible, so that I can help better.
