GoogleBot JS errors and what to do about them?

Question

Googlebot

Hello.
We installed jsnlog on the site and we see a large number of errors:

{"msg":"ClientException","errorMsg":"Uncaught ReferenceError: ymaps is not defined_referer_undefined_userAgent_Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)","url":"...","line number":823}

there is a feeling that googlebot refuses to load Yandex.Maps, no other useragent has a similar error.
Has anyone experienced this and what should I do?
