I'm getting this error when launching on Quilt. Does QFAPI need to update, or is this an Indium issue?

Same issue

pretty sure its QFAPI that needs to update cus its an outdated rendering dependency

QFAPI needs to be updated to incorporate the changes from Fabric API 0.89.0.

https://github.com/comp500/Indium/releases/tag/1.0.27%2Bmc1.20.1

he just pushed an update

the only problem is its not on modrinth yet but thats modrinths problem

annnd it still decides to not work, I'm gonna go out and say this is quilt's problem here

The PR was merged last night. You can download it from the actions tab, or go to this url. It is a zip, so go into /build/libs/quilted-fabric-api-7.2.2+0.89.0-1.20.1 after extracting. It hasn't been uploaded to Modrinth yet, but it should be soon.

Official release is here!
[1.20.1] QFAPI 7.3.0 and QSL 6.1.2
