Capacitor 3 : Blank screen - CreateEvent

[Oupsla]

Hello folks 👋

Trying to upgrade to capacitor 3.0 but encountered an error.
Manage to compile and working great on the web but got a blank screen on both iOs and Android. When inspecting the webview with DevTools, I can see an error : Capacitor.createEvent is not a function in fireWindowEvent

We maybe suspect it comes from capacitor-cordova-plugin but nothing sure (and we didn’t manage to remove the generation of those ones, if someone know how do to it ?)

From Android Studio console :

I/Capacitor/Console: File: http://192.168.1.13:3000/ - Line 331 - Msg: Error in Success callbackId: NetworkStatus1649682775 : TypeError: Capacitor.createEvent is not a function

From Chrome Dev Tools :

Uncaught TypeError: Capacitor.createEvent is not a function
    at Object.fireWindowEvent ((index):235)
    at Object.callbackFromNative ((index):332)
    at <anonymous>:1:9

Did you do this?
https://capacitorjs.com/docs/v3/updating/3-0#importing-capacitorcore

while it says it's "recommended", it's sort of mandatory

Yes already done.

But I found the problem !
My error was to do ReactDOM.render in an async method (cause I had to init some libs before).
I have extracted this outside my async method and it is working great now 😄

For futur readers :

This error was caused (in my project) cause ReactDOM.render was inside an async method. Putting it outside of it has resolved this issue

any solution for angular-ionic apps?
