Environment details

• OS: macOS 15.1 (doesn't matter)
• Ruby version: ruby 3.3.6
• Gem name and version: google-apis-gmail_v1 (0.41.0)

Steps to reproduce

When creating a Filter via the GMail API (Google::Apis::GmailV1) which includes a forward action, this is apparently user-rate limit throttled.

In my Ruby API client I get the following error messages: rateLimitExceeded: User-rate limit exceeded. Retry after 2024-11-12T11:16:42.247Z (Forwarding rules)

Unfortunately, the time returned when to try again is wrong.

My code waits until this time plus a grace period of 60 seconds. When trying at 11:17:42 UTC I get another rateLimitExceeded: User-rate limit exceeded. Retry after 2024-11-12T11:32:42.968Z (Forwarding rules).

Even when I tried the code a couple of hours later, I still get that error on the first request. So the given retry-after time is clearly wrong.

Code example

begin
  @client = Google::Apis::GmailV1::GmailService.new # Authorization code skipped
  criteria = Google::Apis::GmailV1::FilterCriteria.new(…some query…)
  action = Google::Apis::GmailV1::FilterAction.new(forward: "[email protected]") # This is a verified address, cross-checked with list_user_setting_forwarding_addresses
  filter = Google::Apis::GmailV1::Filter.new(criteria: criteria, action: action)
  result = @client.create_user_setting_filter('me', filter_content)
rescue Google::Apis::RateLimitError => e
  puts "Rate Limit Exceeded: #{e}
end
> User-rate limit exceeded.  Retry after 2024-11-12T11:16:42.247Z (Forwarding rules)
