Ads API "Bad metadata value given"

[Remco Aalderink]

We've just started on testing out the new Google Ads API, and have ran into the "Bad metadata value given" error message today. Yesterday, the following code worked:

$configuration = new Configuration($iniFileContents);

$tokenBuilder = new OAuth2TokenBuilder();
$credentials = $tokenBuilder->from($configuration)->build();

$clientBuilder = new GoogleAdsClientBuilder();

$clientBuilder->from($configuration)

  ->withOAuth2Credential($credentials)

  ->withLoginCustomerId([customer ID as int]);

$client = $clientBuilder->build();

$client->getCustomerServiceClient()->listAccessibleCustomers();

But when I started on it again this morning, it threw the "Bad metadata value given" error. I do not see why this has suddenly happened. Any ideas?

Hi,

Thank you for reaching out. To further investigate, could you provide the complete JSON request and response logs when you encountered the error? Please reply via Reply privately to author. If you haven't enabled logging yet, you may refer to this guide as to how.

Hello,

In the meantime, I have figured out what the issue was. I was sending the value of the login-customer-id as an int, which is the PHPDoc typehint in the PHP library, but gRPC expects a string. Once I made the value a string the issue was solved.
