Unable to parse inbound JSON



Unable to map the inbound JSON when the data model inheritance hierarchy has properties with the same name but different types, or properties with same name and same type. Additionally, the Create Rest Integration wizard creates properties with the same name and same type, twice.

Error Messages

Not Applicable

Steps to Reproduce

  1. Run the Create REST Integration wizard and consume the sample response to generate the data model. The sample response must include properties with the same name and different types (for example, a page and page list property with the same name) or properties with the same name and same type.
  2. Invoke the data page to parse the sample response message. None of the properties are mapped.

Root Cause
