Newbie lost trying to get LEDs to work

I built an hyperion ambilight setup but cannot get the lights to work. I'm sure that to someone with more experience, this will be easy to resolve. I've attached the debug log. TIA!

I have a Raspberry Pi4. I followed the Ambilight Tutorial from Chris Majestic. I have BTF-LIGHTING WS2812B LED strip hooked up to the GPIO on the Pi. Here is the link to the tutorial I followed:

Try this and see if it works:

sudo systemctl disable --now hyperion@pi sudo systemctl enable --now hyperion@root

If it doesn't work then go to this link and down to Preparation and installation section (I didn't have to do that with new hyperbian)

It's already running with root.

Do you have a live image in Hyperion?

Yes, I have a live image in Hyperion.

OK.

The problem you see in the log is

2022-05-06T02:53:16.173Z [ LEDDEVICE] (ERROR) Device disabled, device 'ws281x' signals error: 'Failed to open. Error message: Hardware revision is not supported'

Please more information about your system.

You need to update to a newer version of the Ws281x Library. Try Hyperion‘s nightly build.
