verifyElementPropertyValue is not working

Can someone please help me understand why would the following command all of the sudden stop working? Today, I can put ABC instead of “UserResponse” and the return value is still true. For some reason katalon is only verifying “Return.UserId” and any text prior to that is ignored.

WS.verifyElementPropertyValue(response, ‘ABC.Return.UserId’, ‘Jake’)
WS.verifyElementPropertyValue(response, ‘UserResponse.Return.UserId’, ‘Jake’)
