[evaluation ID = bfc87:b5c51] : Expression evaluation error : The function 'isusermemberofgroup' is unavailable. (APNX-1-4198-000)

Has anyone getting this error after Appian upgrade to 21.3. 
I checked in the code where ever isusermemberofgroup function was used it is now appearing as isusermemberofgroup_21r2, still for some user we are seeing above error.

appian update 21.3

Hi Ravi,

Appian has released a new function a!isUserMemberOfGroup() to replace the old function. Hence the version name has been appended to the existing function & it fails in some cases after the upgrade. It is recommended to use the latest function to avoid issues.

Hi Selva,

Thanks for your inputs, changing the function is the final solution however we are looking for the some cases (As you have mentioned) where it is failing.

Thanks

My understanding is that its limited to scenarios where the old isusermemberofgroup() function is used in related actions on record and resaving the record type should stop recurrence of the error. I suggest you raise a support ticket for the affected environment for more info.
