Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential automl

I am a novice developer who wants to learn how to use artificial intelligence. So I created model and it responds correctly according to the inputs. So I want to test using postman a call to the API to verify that everything works and I have an error in my call: "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.", "status": "UNAUTHENTICATED" I don't know how to authenticate myself to retrieve the access token. Could you help me find a solution please?

I've encountered a similar error with Google calendar in SwiftUI. I fixed it by specifying the authorizer info from the signed-in user

let service = GTLRCalendarService()
service.authorizer = user.fetcherAuthorizer
service.executeQuery(insertQuery) { (ticket, object, error) ... }

A full sample app is available in github.

You have 2 solutions:

  • As John commented,
    • Install the gcloud SDK on your computer.
    • Authenticate yourselves with the command gcloud auth login or gcloud init (proposed at the end of the installation)
    • Generate an access token gcloud auth print-access-token and copy it
      • Tips: you can skip the 2 first steps if you use Cloud Shell
    • Add the access token to the header to your Postman request like this:
      • Key is "Authrorization"
      • Value is "Bearer "
    • The access token is valid 1H, then you have to generate a new one.
  • (Not recommended) Make your model public (i.e. unauthenticated) like this (only in command line, it doesn't work on the GUI)
gcloud ai-platform models add-iam-policy-binding --member="allUsers" \
  --role="roles/ml.modelOwner" <Model Name>

replace Model Name by your deployed model. However, it's only for test purpose. You have any filter and anyone can use it and you will pay for the processing incurs.
