Hi Ramachandiran,
I’m not sure why you get the error with the format() function.
But the work around for that could be,
Extract the activity where u use the function into a submicroflow.
And give a error handling type continue for the submicroflow.
Since you stated that you are getting the desired output, this would only avoid the error being thrown at the client side.
Hi Ramachandhiran,
Add a clause to check for empty values as well, as the function will throw exception if the date passed is empty
You might want to check if the Chat_Owner_Account object exists.
The stacktrace is missing the most important part, that were the error is explained.
But I think Prashant is right in his comment, there should be empty checks.
