Service Account giving me heart ache.

[Kevin Mulholland]

I have been working on getting the Google Ads to work with a Service Account. But I just cannot get past the Oauth.

I am using the JSON file that was downloaded when setting up the Service Account. I feel like I have everything set up, but for the life of me, I cannot get going with actually creating any campaigns.

For this project I am using :
PHP 8.0
"laravel/framework" : "^7.30",
"googleads/google-ads-php": "^7.0",
"phpunit/phpunit": "^9.3",
"grpc/grpc": "^v1.27.0",

When trying to run the example code from google Create Campaign Example I get hit with the error "User in the cookie is not a valid Ads user."

"grpc-status-details-bin" => array:1 [ 0 => b""" \x08\x10\x12×\x01Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.\x1A{\n Ctype.googleapis.com/google.ads.googleads.v6.errors.GoogleAdsFailure\x124\n 2\n \x03ˆ\x01\x0E\x12+User in the cookie is not a valid Ads user. """

I also have Logging set up with Laravel's Logging system

$this->googleAdsClient = (new GoogleAdsClientBuilder()) ->withDeveloperToken(config('social.google.client_builder.developer_token')) ->withLoginCustomerId((int) config('social.google.client_builder.linked_customer_id')) ->withTransport('grpc') ->withLogger(Log::getLogger()) ->withOAuth2Credential((new OAuth2TokenBuilder()) ->withJsonKeyFilePath(config('social.google.oauth.json_key_file_path')) ->withImpersonatedEmail('x...@xxx.iam.gserviceaccount.com') ->withScopes("https://www.googleapis.com/auth/adwords") ->build() ) ->build();

The logger puts out this message.

I have been at this for about 3 weeks now and cannot find where I am going wrong. Any and all help is IMMENSELY appreciated!
