Mapping does not occur despite Property Qualifier being present



A JSON based REST-Service is configured. The JSON is mapped to the Clipboard using the out-of-the-box 'Map to JSON' option on the REST service. The mapping does not occur correctly, despite the pzExternalName Property Qualifier existing for some properties.

Error Messages

Not Applicable

Steps to Reproduce

Test the REST Service with Map to JSON option containing Property Qualifiers.

Root Cause

The external qualifiers were not similar to the Pega properties. While parsing the JSON file, the application did not copy the data to the correct properties from JSON to Pega.


As a local-change, rename Pega properties according to the JSON structure.

An enhancement request, FDBK-29822, is created for consideration by Pega Product Management.
