AADSTS70007: UnsupportedResponseMode
  • The response_mode value is not valid for the authorization request.
  • The app is mixing response parameters from different OAuth flows.
  • The library or custom auth code is constructing the request incorrectly.
  1. Review the response_mode value sent in the request.
  2. Match the response mode to the intended auth flow.
  3. Update the auth library configuration if it is generating an unsupported request.
