Hello! From yesterday all of my inquires has stopped working and returning anything even though i'm absolutely sure the data exists. For instance this patent was granted but I cannot get any info. 

https://api.patentsview.org/inventors/query?q={%22patent_number%22:%226128488%22}&f=[%22inventor_id%22,%22inventor_first_name%22,%22inventor_last_name%22,%22assignee_id%22,%22assignee_organization%22,%22assignee_type%22] 

Could you please check what can be a prob?

Thank you!
