I'm using Data Center and Automation for Jira. I have a basic rule that gets triggered on new issue creation and one of the things it does is set priority field. But, it keeps erroring out when trying to set it to what i picked from the pulldown. other fields I can update no problem. one thing i did notice was the the list of choices in the priority pull down when setting the rule is not the same as the priority scheme for this project, it seems to be a superset, like it's using another priority scheme. the scope of this rule is set to just one project. has anyone run into this before?
There wasn't a work-around listed with the ticket. Perhaps try using the JSON edit features and set the field ID to the exact value of the priority you need:
