Hello,
I am trying to create (or reauthenticate) a OneDrive for Business data connection in a client's Power Automate environment. I get the following error:
OAuth2CertificateOneDriveForBusiness authorization flow failed for service 'OneDrive For Business Certificate'. Error deserializing GraphDriveResponseEntity. Exception=System.ArgumentNullException: Value cannot be null. Parameter name: uriString at System.Uri..ctor(String uriString) at ConsentServer.Core.Services.Login.OneDriveForBusinessLoginStrategy.d__7.MoveNext()
My team believed it to be a DLP policy issue as it first arose when importing a workflow, however I get the same error when attempting to create the connection in the connections page, not within a flow. I also tried creating a new flow with only a OneDrive trigger, with no other connectors, and the connection failed again. The OneDrive for Business connector is in the Business group of the policy.
From my understanding of DLP policies I should still be able to create the connection in the connections tab, and should only have issues with the policy when using it in a flow with other connectors. How can I create this data connection? Thanks.
