Many errors from googlebot

Hi! I am using JS SDK. At last time (~ two days ago), I am recieving many errors with message “Cannot call a class as a function”. The errors have not any context data (and url too) besides ip. Ip are equal:
i.e. 66.249.. ( - googlebot).

How can i filter that errors or maybe fix ? I tried to use ignoreErrors, but it didn’t help. (p,s, I’ve enabled “Filter out known web crawlers”). Thanks.
