If you are having problems in getting the tests to pass, make sure that its is not due to CORs validation. Look at the allowedOrigins in fcctesting.js and add the domain - In my case, I had to add "https://www.freecodecamp.org" and then the tests started to pass.

i think connected in line 68 should be "false"

i think connected in line 68 should be "false"

So do I.
