Error in the console output in Safari (Chrome is OK)

EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "default-src 'self' http: https: data: blob: 'unsafe-inline'".

Can somebody check why there appears this error while editing/running my code ? Thank you.

Normally, bugs should be reported as GitHub Issues, but @freeCodeCamp tweeted this morning:
We are still doing some maintenance on freeCodeCamp. If you notice anything weird happening, please reply to this tweet and we can investigate it. Thanks for your patience.

It looks like @caseypitman11 has already reported this issue with Safari:

I will update the banner at the top of the forum to include that there are issues with Safari.
