Cause

The error code RSA003 means that the REST Web Service request completed and returned a result.  The most likely cause of error code RSA003 is that the Expression Pattern is incorrect. The result may have been a success but the REST Web Service node was unable to parse the response from the Response Variable.
 

Resolution

To resolve the issue,

1. Edit the custom Workflow that processes the request. 
2. Edit the workflow REST Web Service node. 
3. In the RESPONSE section, edit the Error Variables.   
4. Select the Error Response variable open it in the editor.
5. Modify the Expression Type (XPath or RegEx).
6. Modify the Expression Pattern to ensure it matches the expected substring of the response.
