Thanks for pointing that out! I know it must be hard for all the staff at FCC to keep all the documentation up to date. Hopefully someone can put up that new URL on the wind-bow page. The old one is still there.
My fetch does not work as I had it written, and to get it to work I had to remove the headers. But now it does work!
The setTimeout was a hackey way to do it and thanks for showing me a better way as well.
