Hi I use the same ClientConn to send a request, one of which is successful, but the other fails
The prompt when it failed was : ```bash rpc error: code = Unauthenticated desc = Request 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. ``` This is my code: ```go headers := metadata.Pairs( "authorization", "Bearer "+accessToken, "developer-token", developerToken, "login-customer-id", customerID, ) ctx := context.Background() ctx = metadata.NewOutgoingContext(ctx, headers) cred := grpc.WithTransportCredentials(credentials.NewClientTLSFromCert(nil, "")) conn, err := grpc.Dial("googleads.googleapis.com:443", cred) ``` ```go customerServiceClient := services.NewCustomerServiceClient(conn) accessibleCustomers, err := customerServiceClient.ListAccessibleCustomers( ctx, &services.ListAccessibleCustomersRequest{}, ) ``` I can get the correct return information from ListaccessibleCustomers ```go campaignServiceClient := services.NewCampaignServiceClient(conn) campaigns, err := campaignServiceClient.MutateCampaigns(ctx, campaign) ``` Campaign objects have been created in the code Mutatecampaigns will prompt me to lack authentication Is there a different verification method different interface?
