Reproduce

• Deploy process application which contains a decision and a custom java class (example: https://github.com/menski/dmn-rest-complex-object)

• Evaluate decision directly through REST API /engine-rest/decision-definition/key/testDecision/evaluate with a serialized value of the custom java class, e.g.:

  {
  "variables": {
      "claim": {
          "type": "Object",
          "value": "{\"type\":\"Unfall\"}",
          "valueInfo": {
              "objectTypeName": "org.camunda.bpm.example.Claim",
              "serializationDataFormat": "application/json"
          }
      }
  }
  }

• Error:

  java.lang.IllegalStateException: Object is not deserialized.
