Process Trigger With Id Does Not Exist Issue – RibbonWorkbench :
Recently, When we are publishing the entity in Ribbon workbench after making some changes, It has thrown the exception ” Process trigger with id Does Not Exist “.
This is due to Business Rules of that particular entity with scope for a particular form.
Solution: Change the business rules scope to “All Forms” and change them back after the ribbon customization import.
It will work. Enjoy 🙂
