Publish successful, not able to trigger in Azure Synapse Analytics

I have a set of Notebooks and pipelines in Azure Synapse pipelines, which are working when I debug. Publish is also successful, but when I trigger the pipelines, it says that "Pipeline is not found, please publish first" as in below screenshot!

When I use Trigger Now option, it shows below image!

I disconnected Git at backend, and reconfigured the new branch, but unfortunately the same issue again. I am publishing from my collaboration branch. All my Notebooks and pipelines are in collaboration branch!

Can someone, please help me what is wrong here?

This is normally an issue to be handled by the support team, but my idea is changes to the master branch are not being published correctly, as I have seen a similar case before.

your synapse pipelines (which is in essence ADF) was working with old metadata/code and never updating as it should, hence why it worked in debug mode (current/new metadata) but not with triggers (published metadata/code). This seems to be a rare kind of issue or bug.

Try recreating the linked services and connection then replace it in the datasets. Recreating the resources (linked service etc) should fix it.
