Blur my background not working

We have setup standard Jitsi and we build Jitsi-meet using source code with few customization in jitsi-meet react code. We use “make” command to build the project on server. The only broken functionality is “blur my background” functionality.

When we try to use the option, below message appear in console.

[features/blur] getBlurEffect failed with error: TypeError: Cannot read property ‘createBlurEffect’ of undefined
