authenticate_oidc: No client_id found (when OIDC provider does not list refresh_token grant type)

I have a backend with the following response to GET /credentials/oidc:

{
  "providers":[
    {
      "id":"google",
      "issuer":"https://accounts.google.com",
      "title":"Google",
      "description":"Login with your Google Earth Engine account.",
      "scopes":[
        "openid",
        "email",
        "https://www.googleapis.com/auth/earthengine"
      ],
      "default_clients":[
        {
          "id":"123.apps.googleusercontent.com",
          "grant_types":[
            "implicit"
          ],
          "redirect_urls":[
            "https://editor.openeo.org/",
            "http://localhost/"
          ]
        },
        {
          "id":"abc.apps.googleusercontent.com",
          "grant_types":[
            "urn:ietf:params:oauth:grant-type:device_code+pkce"
          ]
        }
      ]
    }
  ]
}

I'm running:

import openeo
connection = openeo.connect("http://localhost:8080")
connection.authenticate_oidc()

And get unexpectedly the following error:

OpenEoClientException: No client_id found.

Why is that? I think there's a reasonable default client ID available. (All client IDs are placeholders in the example.)
