I have a solution which suppose to display an error message from a plugin on an update a CRM entity in an advance form of the portal. This solution was working for two year but recently we notice that the portal does not displays the custom error message any more rather it displays the generic error message:
An unknown failure has occurred. Error ID # [7befa246-86f4-4410-8924-b9c92b413828].
We are on the latest Portal version 9.2.2108.0
and “Site/EnableCustomPluginError” is set to true
Any idea on why we cannot see custom plugin error message in the portal?
