Redirect to interface

Question

Hi All, 
 
 My requirement is if any error comesup then it has to redirect to the same interface to modify the form and then resubmit the form again . IN the 2nd interface (which is same as 1st) I'm getting the below error .can someone please help. An error occurred while evaluating expression: Error.message:AC!error.body (Invalid index: Cannot index property 'body' of type Text into type IntegrationError) (Data Outputs)

Can you try the following to rule out error.body existence in process model as well. Go to Process Documentation and search (ctrl+f) error.body or just body and see if you find something. For Documentation go to Tools->Generate Documentation

First check the input node then expand the error variable. there check the saveinto config of message input. 
 Also check the output tab on UIT if any configuration is there.

The error is happening because you're trying to use ac!error.body in the Data Outputs tab of your User Input Task, but Activity Class parameters (ac!) aren't available in User Input Tasks - they only exist in Script Tasks and other system nodes. In User Input Tasks, you can only map rule inputs (ri!) from your interface to process variables (pv!).
To fix this, remove the ac!error.body reference from your Data Outputs tab. Instead, capture the error in a Script Task or Integration node before the User Input Task, save it to a process variable there, then pass that process variable to your interface as a rule input. This way, you're only mapping ri! values to pv! values in the Data Outputs, which is the correct approach.
