it takes me to https://legacy.gitbook.com/book/kdchang/react101/details

If I click on  https://www.gitbook.com/book/kdchang/react101/details

it keeps on taking me to https://legacy.gitbook.com/book/kdchang/react101/details
(LEGACY website)

and then it will not let me see the book, but ask me to Sign up

And Sign up says, New User cannot be created on the Legacy website
