InboundMappingException while formatting returned JSON data



InboundMappingException while formatting the JSON data returned from the Pega API Get Data option. This occurs when the data type references a report definition.

Error Messages Exception occurred while mapping incoming response to .ASReleaseList

Error shown by JSON Validator:
"pyNeedleTopWidth": "0",
"pyNumberCurrencySymbol": "#DIALOGBODYquot; ,"
pyNumberFormat ":"
Error: Parse error on line 803:
...OGBODYquot; ," pyNumberFormat ":"
Expecting 'EOF', '}', ':', ',', ']', got 'undefined'

Steps to Reproduce

  1. Create a REST connector which references the out-of-the-box GET Data API
  2. In the endpoint URL, specify a data type which directly references a report definition
  3. Create an activity to call the REST connector
  4. Run the activity and trace
  5. View the error in the tracer, or if the response is set to clipboard, copy the JSON from the returned field and enter into a JSON validator

Root Cause

The Service returns the JSON representation of a Code-Pega-List object, which is not an Array of objects. 
However, the connector is configured for JSON mapping to a Page List property.


Perform the following local-change:

Reconfigure the service to send a valid JSON Array of 'PegaProjMgmt-Work-Product-Version' objects, by serializing the pxResults property to JSON rather than the whole Code-Pega-List page. 

Alternatively, reconfigure the connector to map to a single Page of type Code-Pega List, and then reconfigure the application logic to consume the pxResults property of this page.
