Getting oauth token http header is malformed

[Chris Lin]

Been trying to make a simple campaign reports using PHP/Laravel, tried to follow docs and search on Google but running into a wall. Is there a way to find out what the actual headers are being sent? I pieced together the code from the help docs and random google searches, feels like I am missing something basic?

The error is below:

  -metadata: array:1 [
    0 => array:3 [
      "@type" => "type.googleapis.com/google.ads.googleads.v16.errors.GoogleAdsFailure"
      "errors" => array:1 [
        0 => array:2 [
          "errorCode" => array:1 [
            "authenticationError" => "OAUTH_TOKEN_HEADER_INVALID"
          ]
          "message" => "Oauth token HTTP header is malformed."
        ]
      ]
      "requestId" => "eZJRtqwznPOdfR-5M_9sgA"
    ]
  ]

  $oAuth2Credential = (new OAuth2TokenBuilder())
                ->fromFile(storage_path('google_ads_php.ini'))
                ->build();

            $googleAdsClient = (new GoogleAdsClientBuilder())

                ->fromFile(storage_path('google_ads_php.ini'))
                ->withOAuth2Credential($oAuth2Credential)
                ->withDeveloperToken(env('GOOGLE_DEVELOPER_KEY'))
                ->withLoginCustomerId($this->managerCustomerId)
                ->build();
            $query = 'SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id';
            $response = $googleAdsClient->getGoogleAdsServiceClient()->searchStream(
                SearchGoogleAdsStreamRequest::build($customerId, $query)
            );

I just cloned this app https://github.com/googleads/google-ads-php/tree/main/examples/LaravelSampleApp and set it up and get the same error. Is it possible it's my google_ads_php.ini? I left the contents of it below with the credentials masked out, one of the requestIds was "e87P3kSbIgA-m-oFOB325Q"

[GOOGLE_ADS]
developerToken = "XXXXXXXXXXX"
loginCustomerId = "XXXXXXXXXXX"

[OAUTH2]
; For service account flow.
jsonKeyFilePath = "VALID PATH TO JSON"
scopes = "https://www.googleapis.com/auth/adwords"
impersonatedEmail = "x...@xxx.xxx"

Solved it, developer key was incorrectly typed in
