Error Message: Can't update Price Book.

Hi,
I am receiving the following error message when trying to add a Product to a Renewal Opportunity:

"Can't update Price Book. Unexpected exception while validating invocable action requests"

I have recently implemented a few Flows for the Opportunity object, but none of those Flows include any fields related to Price Books or Products. Once I deactivated one of those Flows (to standardize the Opportunity Name), I was able to add a Product to the Opportunity, no problem.

Does anyone have any insight as to why this Flow would be causing an issue with the Products and Price Books if the Flow was seemingly unrelated?User-added image

Hi Jewels,

I believe when referring to flow, you are referring to Trigger Flow. Trigger flow executes on the action (insert, update, delete) happens on the object, triggers are built for and not on the field level. So It doesn't matter if the field is part of the flow or not, it will trigger. Please check your flow criteria skipping such record going into your flow.
