The issue got resolved after clicking on "Update Record" on our QA environment after importing the application.

Hi Nikhil, we are using 7.10 but we are still getting the same error. How can we update the record? Thanks!

Hi Omkar, DId you check the application server log? We dont have Update Record anymore, what you can also try is by reducing the expression to a test one, which does not reference any process objects and narrow down the root cause.

Thanks Nikhil!
