Yes, i also faced this problem, what i did was if file size was > 100kb then i delete cookies and bot will check if cookies are not present then it will call login function and new cookies file will be saved which will be less than 100 kb.
@sergerdn thanks for info, i was hoping there would be a prebuilt extension that would accept bas cookies.
This extension will handle the conversion of cookies from the Chrome-based browser(BAS browser) to their respective format for Chrome. With this extension, you won't need to worry about the internal cookie format used by BAS.
