PowerAutomate, Create a new task -->The response is not in a JSON format.

[Manuel13]

Hello,

I would like to create a new task in the planner directly from project.

Once I define the "Root Site URL" of my project and test the flow, I get following error message.

I tried to fix it but I'm lost...

Error details:

The response is not in a JSON format.

"error": {

    "code": 404,

    "source": "flow-apim-europe-001-westeurope-01.azure-apim.net",

    "clientRequestId": "cdbad09c-412b-45a4-ad73-7c03eb3288d0",

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

    "innerError": "Cannot read server response."

Thank you:)

Hi Manuel13

The 404 error usually represents connection authorization.  Could u share your error details regarding "Root Site URL" of project? You could also check whether your connection credentials have right access to the plan project.
