[SOLVED] ACCESS_TOKEN_SCOPE_INSUFFICIENT error with Google Analytics Data GA4 runReport request

We are receiving an error ACCESS_TOKEN_SCOPE_INSUFFICIENT when trying to run the runReport method with the Google Analytics Data GA4 API. As you can see in the debugging dump, have all necessary scopes in the authorization to make the request:

Request:

curl -X POST -H "User-Agent: python-requests/2.27.1" -H "Accept-Encoding: gzip, deflate" -H "Accept: */*" -H "Connection: keep-alive" -H "Content-Length: 399" -H "Content-Type: application/json" -d '{"dateRanges": [{"startDate": "2022-04-25", "endDate": "2022-04-25"}], "dimensions": [{"name": "date"}, {"name": "eventName"}, {"name": "sessionDefaultChannelGrouping"}, {"name": "sessionSource"}, {"name": "source"}], "metrics": [{"name": "eventCount"}, {"name": "eventValue"}, {"name": "newUsers"}, {"name": "sessions"}], "metricFilter": null, "dimensionFilter": null, "limit": 100000, "offset": 0}' 'https://analyticsdata.googleapis.com/v1beta/properties/264786259:runReport?access_token=REMOVED'

Response

            }
        ]
    }
}

Note: Unnecessary use of -X or --request, POST is already inferred.
