I am trying to run the built in flow for Microsoft's Insider Risk Management - "Notify manager of insider risk alerts for user." The flow is failing with error

Action 'Get_Insider_Risk_Management_case' failed

{

"error": {

"code": 403,

"source": "flow-apim-msmanaged-na-westus2-01.azure-apim.net",

"clientRequestId": "[redacted]",

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

"innerError": "Cannot read server response."

}

Has anyone else experienced this error/ figured out a way around it? This is triggered when a case is created and I manually have a case selected to run the flow.

The (HTTP) code 403 means access forbidden, so this will be a permission issue.

Thanks for the reply. I am wondering if it is an issue that the account running the flow is different from the account used for the connections?

For instance, account aGoodguy is the owner of the flow and used to connect to Microsoft 365 Compliance, Outlook, and Office 365 Users.

Account aBadguy is set up as a Run-only user and for the connections is told to use aGoodguy's connections.

Abadguy runs the flow and gets the 403. I've even seen this error on trying to resubmit:

Request to Azure Resource Manager failed with error: '{"error":{"code":"InvokerConnectionOverrideFailed","message":"Could not find any valid connection for connection reference name 'shared_microsoft365compliance_2' in APIM tokens header."}}'.

I am having a similar error. I have a flow that ran successfully for me, but when I have a 'run only' user run the flow it fails. I checked the connections and it is connected as me. Below the output it says Connection: <my email address> with a green checkbox.

"error": {
"code": 401,
"source": "flow-apim-europe-001-westeurope-01.azure-apim.net",
"clientRequestId": "redacted",
"message": "The response is not in a JSON format.",
"innerError": "Cannot read server response."

@MTGraves HTTP 401 means unauthorized, so the user running the flow is not authorized for the datasource used.

An instant flow will run under the users credentials, not the credentials you used to configure the flow.

Thanks shoog. I checked that the run only user has access to the workspace, data set and report. There was an additional workspace I had to add them to for the actual paginated reports and the job ran successfully.
