I have inherited a rest API dataflow from a developer who left the company. It was working flawlessly but suddenly stopped working the other day. I took over the dataflow in the app but am having difficulty authenticating using our service provider. We have the App registration setup in Azure, the service provider is in a group that has access to the Power BI workspace. I am using the Client ID as the Service Principal ID, the Tenant ID as the Tenant ID and I have the secret for the Service Principal Key. I am getting the error: "Failed to update data source credentials: Failed to get OAuth resource, please make sure the OAuth is supported." I am new to APIs in general as well as Power BI. Any advice on where I should start troubleshooting. Thanks in advance for the help!
