RESOURCE_EXHAUSTED Quota exceeded but couldn't have possibly hit the quota

[Erik Chan]

{"error"=>{"code"=>429, "message"=>"Check Error: RESOURCE_EXHAUSTED Quota exceeded for quota group 'billable_default' and limit 'General model characters per user per 100 seconds' of service 'translate.googleapis.com' for consumer 'project_number:689493101183'.", "status"=>"RESOURCE_EXHAUSTED"}}

My quota for general model characters per user per 100 seconds is 10,000,000 (confirmed this with my project number), I don't think I am hitting the quota as my text is ~220,000. 

What could the issue possibly be?
