[BUG] Unhandled Promise Rejection when run on Docker

[nguyensonghao94]

chrome-aws-lambda is working very good but when we run on some website we has an error

" Unhandled Promise Rejection {"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"TypeError: Cannot read property 'errorText' of null","reason":{"errorType":"TypeError","errorMessage":"Cannot read property 'errorText' of null","stack":["TypeError: Cannot read property 'errorText' of null"," at Page.

And when we use puppeteer it still working

@nguyensonghao94 Can you clarify if you're getting this error on a specific URL?

From your report it's not clear whether this is happening only on Docker or only on a specific URL.

Please share more details, I'll be glad to help.
