What browser are you using? Have you checked for updates?

Errors like this are usually caused by an out-of-date or unsupported browser.

I am using safari.

This is the first time something like this has happened.

Hey there, I’m dealing with the same issue on Safari Browser. Try using Chrome or other browsers.

They must have changed something in tests what is not supported in Safari yet

It looks like there’s a Safari related bug right now.

Bugs can be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.

For now you can use Firefox, Chrome, or Edge - or you can skip this challenge.
