Creating Metadata Adjuster

[Furkan KAMACI]

Hi Folks,

I'm trying to test creating a job with a transformation (metadata
adjuster). Everything is OK except for transformation. Here is what I send:

      {
        "stage_id": "1",
        "stage_isoutput": "false",
        "stage_connectionname": "My Existing Connection",
        "stage_description": {
          "expression": {
            "_attribute_parameter": "my_type",
            "_attribute_value": "Dummy Expression"
          }
        }
      }

I can see that transformation is created and added when I check the UI.
However its metadata expressions is empty. What I miss?

Kind Regards,
