Virtual Background: unknown message in single thread vb worker

Video SDK
1
  • Video SDK Type and Version*
    1.11.0, 1.10.7

Description
I’m currently trying to implement blurred backgrounds. I’m doing this without SharedArrayBuffer. Console logs indicate the virtual Background worker is failing. The video does start, but with no blur or background image. The current relevant code is very simple:
await zoomClient.init(‘en-US’, ‘Global’, { patchJsMedia: true, enforceVirtualBackground: true });
await zoomSession.startVideo({ virtualBackground: { imageUrl: ‘blur’ } });

Error?
On initializing and connecting to zoom, I receive the first error “unknown message in single thread vb worker: undefined”, then when starting video I receive the second error "unknown message in single thread vb worker: vb "

unknown message in single thread vb worker: undefined
value @ 33a15246-0f4e-4591-a68f-aded56b8d0f2:1

unknown message in single thread vb worker: vb
value @ 33a15246-0f4e-4591-a68f-aded56b8d0f2:1

Troubleshooting Routes
I upgraded the version from 1.10.7 to 1.11.0. I also tested with an input image which resulted in the same messages.

Browser
Chrome version: 124.0.6367.119
