Foundry v9 canvas doesn't load with STV enabled

[TheTural]

Just logging an issue since during my testing I found that SVT was causing the Foundry canvas to fail to load in the upcoming v9 release.

Disabled all other modules for testing, canvas is just gray with STV enabled. The console doesn't give a very specific indication of what may be wrong (or I'm not smart enough to identify it from this). Only error in the console during a scene load:

Thanks for the stack and the report, I'll try and see if this is something small I can fix in the next week. I am not up to speed on the v9 breaking changes (life has interfered with my RPG and Foundry time since the fall) - if it's a substantial break I may need to solicit help for this one and declare v9 unsupported for a while.
