Lib-jitsi-meet Uncaught TypeError: Super expression must either be null or a function

Hello
I am getting such blocking issue when accessing my web app using lib-jisti-meet:

b446e5f1f8879fb8aec7.js:2 Uncaught TypeError: Super expression must either be null or a function
    at b446e5f1f8879fb8aec7.js:2
    at b446e5f1f8879fb8aec7.js:2
    at Object.<anonymous> (b446e5f1f8879fb8aec7.js:2)
    at Object.<anonymous> (b446e5f1f8879fb8aec7.js:2)
    at n (b446e5f1f8879fb8aec7.js:2)

Error message is not really explicit but gives access to minify script where it occurs.
It looks like this is happening in lib-jitsi-meet/modules/xmpp/ChatRoom.js in the constructor() method.

I hope you guys can help me on this one as I am not sure why it started suddenly appearing.

Thank you
Fabrice

What line?

One thing which was weird was that the app was breaking with such error when being built on external server but was not breaking when built locally. So I thought it could be linked with Nuxt (doing the build and serve of our vueJS app) so I updated Nuxt from 2.4.0 to 2.4.9 and it fixed the issue…
So I am not 100% confident this could not happen in the future again but for now looks like such Nuxt upgrade made the trick…
Thank you
