Thank you for your reply. We have found the cause of the problem. A colleague reset the developer token, causing the original token to become invalid. After replacing it with the new developer token interface, the interface runs normally.

After reviewing your query, I understand that you are getting the error " OAUTH_TOKEN_HEADER_INVALID <https://developers.google.com/google-ads/api/reference/rpc/v15/AuthenticationErrorEnum.AuthenticationError#oauth_token_header_invalid>" in the production environment. It appears that the credentials sent in your HTTP request are not valid and this is why you have encountered this error. The prevention tip recommended is to make sure you've passed the correct access token associated with your account. It's sometimes confused with refresh tokens and authorization codes. If you would like to get a credential that can access all client accounts under a manager account, make sure you get the refresh token <https://developers.google.com/google-ads/api/docs/first-call/refresh-token> for the manager account. For more details, see our guide on access token and refresh token <https://developers.google.com/google-ads/api/docs/oauth/internals#access_and_refresh_token> and OAuth2 <https://developers.google.com/google-ads/api/docs/oauth/overview>. If the issue still persists, please provide us with the complete API logs ( request <https://developers.google.com/google-ads/api/docs/concepts/field-service#request> and response <https://developers.google.com/google-ads/api/docs/concepts/field-service#response> with request-id <https://developers.google.com/google-ads/api/docs/concepts/call-structure#request-id> and request header <https://developers.google.com/google-ads/api/docs/concepts/call-structure#request_headers>) generated at your end to better assist you. If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using.
