I am trying to create a flow that gets data from an existing AGOL feature layer. When I add the action to my flow, I am getting the below error. I have tried entering in the itemID and using different actions from the list of ArcGIS actions and get the same error with each.
(Could not retrieve values. The dynamic invocation request failed with error: {
"error": {
"code": 400,
"source": "power-apis-usgov001-public.azure-apihub.us",
"clientRequestId": "174677bd-700e-43ef-acea-6592d0529d29",
"message": "The response is not in a JSON format.",
"innerError": "Authentication failed. Your session has expired. Please log in again to continue."
}
}.
