Getting error at- a!UserCardUiContents function

Question

Hi All, 
 We're getting an error like- "Expression evaluation error at function- a!UserCardUiContents: The user does not exist." No object has been mentioned in the error mail to identify where the error is occurring. May I know please when this error generally occurs and how to resolve it. 
 Thanks

That function is some internal one. I suggest to open a support case.

Most probably you are receiving this error on a user field. It occurs when passing null/invalid/deactivated users. Add null checks before user functions.

 You can try checking the logs to understand the when about this. Also it can help you identify which parent process or UI is affected to further investigate upon.
