All fields seperated with “” and insted of equal it needs to be :. Please Advice me how to proceed further. Thanks in Advance.

Answer 1

The output of a DMN is a List of Maps (JAVA). What you need is JSON.

So you need to add an Output Mapping to your Business Rule Task.

Something like this:

JSON(JsonOutput.toJson(dmnResult)) > the JAVA result dmnResult is translated to a Groovy JSON and then in a Camunda-JSON (Spin-JSON).
