Error 400 / "The response is not in a JSON format" when trying to update a Cognitoform entry

Hi

 

I am using the Cognitoform connector to write form entries on Cognitoform to a Dataverse table. This works flawlessly. Now I would like to do the reverse and write changes in the Dataverse table to Cognitform using this flow:

I always get the following error message on the "Cognito Update Entry" part

 

{

  "error": {

    "code": 400,

    "source": "flow-apim-europe-002-northeurope-01.azure-apim.net",

    "clientRequestId": "a4cd15f0-f70a-42d3-bdde-f5fe4f513918",

    "message": "The response is not in a JSON format.",

    "innerError": "Cannot read server response."

  }

}

 

I understand this response this could be any kind of issue. Is there any way to know more in detail what happened? Or do you have any hints what I could have done wrong?

    Hi @Andreas029 ,

    Did you tried manually instead of trigger first try to do it manually using instant flows, if it is working then we can able to resolve this.

    Hi Ahammad

     

    I tried it with a manual flow and a hard value for the ID. Unfortunately with the same result
