According to the simple error handler when you wrie a non-zero value to the  error code terminal it will be considered as an error (See the help). In your case you are connecting the Task ID to the Error code terminal, Since your task ID is a non-zero value you are getting the error. You must not connect the Task ID to an error code terminal as it is totally irrelevant and you may end up seeing a different error message leaving you in a confused state.
