Hi @BigToeKnee810 (interesting screen name) I haven't used the script myself, but, just curious if you've set up a Config Profile for these Macs to have FileVault Recovery Key redirection? Its toward the bottom of the payloads list when setting up a Config Profile. See image below

You need to set it to the following option:

I'm pretty sure that is a requirement to have any new keys redirected and escrowed back to the JSS, but again, I haven't really looked at the script created by homebysix to know for sure. Maybe I'm wrong, but I'd at least check into that avenue, assuming you don't already have that profile setting in place.
@BigToeKnee810 Yes, what @mm2270 says is correct... you have to have that configuration profile set up like he mentioned in order for it to work and redirect the Keys back to the JSS. Otherwise, it will just fail.

Yep that is currently enabled.

Weird. It's working this morning, just tried out of curiosity.
