Browser is crashing when recording steps against specific application

When start recording against specific app using extensionless browser, the browser crashes and we are not able to proceed with the recording. The error displayed in the browser console and in Test Studio log is :

Page Error: Error: Bootstrap tooltips require Tether (http://tether.io/)

Hi John,

The issue was investigated in further details and I wanted to follow up some additional details. The initial assumption that the misbehavior is related to the errors in the browser console is not relevant - actually those errors appear also without Test Studio.

Anyways, the reason for the page crashing when trying to automate it is that by design Test Studio disables CORS for the purposes of testing. The issue with the particular page is that there are some Preflight checks which are skipped due to this specific and we assume it most probably caused the page to crash.

At this point we don't plan to change Test Studio behaviour because this will impact how it handles cross origin Iframes, so I have to admit that the current issue will not be addressed.

Thank you for your understanding.

Regards,
Elena
