bug: Firebase dynamiclink event not fired in ios

[karen1au]

Bug Report

I'm using the cordova-plugin-firebase-dynamiclinks plugin and it works smoothly in Android, however in iOS i got this in the log:

 [Firebase/Analytics][I-ACS023001] Deep Link does not contain valid required params. URL params: {
    amv = "";
    apn = "com.example.app";
    ibi = "com.example.app";
    ifl = "https://exampleproject.firebaseapp.com/__/auth/action?apiKey=xxxxxxxx&mode=signIn&oobCode=xxxxxxxxxxx&continueUrl=https://example.page.link&lang=en";
    link = " "https://exampleproject.firebaseapp.com/__/auth/action?apiKey=xxxxxxxx&mode=signIn&oobCode=xxxxxxxxxxx&continueUrl=https://example.page.link&lang=en";
}

FirebaseDynamicLinksPlugin is init, and onDynamicLink was called on launch.
In debugger, it seems that swizzled_application:(UIApplication *)app openURL and swizzled_application:(UIApplication *)app continueUserActivity were never triggered, I'm trying to follow the flow of handling the dynamic link but since I'm not an iOS developer it's quite confusing for me.

I'm not sure if this is the right place to report/ask or if I should post this to ionic-native or the original cordova plugin repo... please let me know if it's not related to capacitor, thanks!

Capacitor Version

  @capacitor/cli: 2.4.2
  @capacitor/core: 2.4.2
  @capacitor/android: 2.4.2
  @capacitor/electron: 2.4.2
  @capacitor/ios: 2.4.2

Platform(s)

iOS

Current Behavior

When launch app in XCode, FirebaseDynamicLink plugin is init and onDynamicLink is called, clicking the url from browser, it doesn't open the link in the app. After I configured associated domains with applinks:example.page.link it does open the app (since this part is not in the doc for the plugin, i'm not sure if it's actually required?) but the callback is not executed, in the log I see [Firebase/Analytics][I-ACS023001] Deep Link does not contain valid required params.

Expected Behavior

Clicking on link in browser should redirect back to app and continue with the sign in process (i'm using dynamic link for authentication)

Other Technical Details

npm --version output: 6.7.0

node --version output: v11.14.0

pod --version output (iOS issues only): 1.9.3

Additional Context

I also have this issue, I can use the deep link open my app in safari browser, but I can not get the url from " App.addListener('appUrlOpen', (urlOpen: any) ", and it works perfect on Android , maybe it relate to IOS14.

The plugin has a category on AppDelegate.m file, but Capacitor has AppDelegate.swift, so the code on the category is not executed.
You'll have to check what the plugin does and try to execute the same code on your AppDelegate.swift
