Hi I’m using Angular12 with Cordova10(monaca/onsenUI) project.
Now I'm getting weird result between browsers that I can't completely access firebase with iOS.

Dependency

"@angular/cli": "~12.2.1"
"cordova": "^10.0.0"
"firebase-tools": "^9.20.0"
"firebase": "^9.1.2"
"@angular/fire": "^7.0.4" // 7.1.0 also can't.
"ngx-onsenui": "^7.0.0"
"onsenui": "^2.10.10"

Problem

Situation

Android : Can access to firebase
Web(macOS..chrome/Safari) : Can access to firebase
iOS : Can not access to firebase

iOS, I am using WKWebView.
I thought CORS maybe problem but I can display firestorage img by URL in my iOS app.
(It may not showing there's no CORS error...)

Having this problem for a long time and can't find solution anywhere...

Log

I can only get log says "Script error".

Want to ask!!!!

・How can I debug more deeper for @angular/fire?
・Do you have any idea why the error happen only in iOS?

Please help me...!!!!
