Issue/Introduction

The Apply DFDL Transformation Assertion parses message/data using a saved-parser generated from a pre-compiled DFDL schema and produces an XML or JSON infoset as its output (Parsing) and also unparses XML or JSON infoset back to its original form (Unparsing).

If you are not using the correct version of the DFDL Assertion and / or are attempting to use a Parser created with a version of Daffodil prior to 3.3.0 then you may see the following error while managing your DFDL Processors through the API Gateway Policy Manager
