Schedule cannot trigger on master branch

Hi All,
I encountered same issue as topic “Schedules won’t start for certain Branches”(2 years ago), but none replied yet.
Same code can trigger jobs on other branches but cannot on master branch.
Anyone have any advice? Thanks

I found the root cause.
There is a job will be triggered on default branch(master), and it needs another job which will not be triggered when schedule. Thus the pipeline failed to create.

Hope this would help someone have same issue.
