Our users began to encounter the following error when trying to turn on the webcam.

The problem turned out to be that I passed these options to the startVideo() method by default:  
`{ virtualBackground: { imageUrl: undefined }}`

The error looks like they have sharedArrayBuffer turned off, but it is turned on, this can also be seen in the screenshot.

Zoom Video SDK 1.4.0

Hi @efron.vit,

Thanks for reaching out with this. To make sure I understand you correctly, were you able to resolve the issues of users not being able to turn on their webcam, and the issue now is what seems to be a misleading error message?

Thanks,  
Rehema

Yes =)  
Since I figured out the problem, I decided to tell the developers what they would mean.
