Not sure why this works, but have been following the homebridge discord and github and this seems to fix it for them. I tested locally on my HA and can confirm this fixes the garage door open/close commands for me as well. Can you test if this works on your end?
Nevermind...seems you have already got it working. Changed header back to the way you had it and it is still working. Thanks for getting this up again so quickly!
