Hi! After upgrading to Three.js 170, I got this error in console:

I believe this is because of this

mrdoob/three.js@ac963e2#r148635345

it is a bug in troika-three-utils ultimately

[RenaudRohlinger]

Submitted a PR to fix an issue in Three.js:
mrdoob/three.js#29789

[lojjic]

FYI it's fixed / worked-around in troika-three-text/utils 0.50.3.

Thank you for the analysis @FarazzShaikh

[FarazzShaikh]

They’re reverting the breaking change in the next patch I believe. So we’ll need to revert the workaround in our libraries as well 😅
