Demystified Process Errors for Your Users
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
Why: Previously, here’s what a user would see while creating a lead and a process tries to create a related opportunity that fails a validation rule. Notice the unhelpful flow version ID and redundant statements about unhandled faults and contacting your admin. Sorry about that.
Now, for that same validation error, users get information that they can act on. Users for whom the information is too complex can share it with their admins to help troubleshoot.
