Firebase dynamiclink event not fired in ios

[karen1au]

it works smoothly in Android, however in iOS when I launch app in XCode, FirebaseDynamicLink plugin is init and onDynamicLink is called, clicking the url from browser 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 for authentication is not executed, in the log I see this:

 [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";
}

Same here

Same problem similar error message:
7.1.0 - [Firebase/Analytics][I-ACS023000] Deep Link Web URL query is empty
The plugin seems to refer to Firebase/Analytics ~> 7.0.0, so perhaps the issue is with version 7.1.0

Update: version 7.0.0 yields the same error.
Here's someone with the same issue, who digged a bit deeper: stackoverflow.

Update:

I'm neither iOS nor Objective-C expert, but I've spent some time digging through the code and came up with a workaround: check out my fork here. Unfortunately, it still doesn't work with cold start (e.g. the app doesn't receive the link if the app was not running).

There are a plenty of challenges here involved: method swizzling doesn't work (in AppDelegate+FirebaseDynamicLinksPlugin.m) and I'm not exactly sure why. Could be because Capacitor initializes the plugin too late, so the swizzling doesn't really work, or could be because main Capacitor app is written in Swift. Also, Firebase-related pods seem to rely on GoogleUtilities which includes its own method swizzling (e.g. in GoogleUtilities/AppDelegateSwizzler/GULAppDelegateSwizzler.m)`.

I think someone with better iOS-dev background should take a look.

If you're also using Capacitor, considering this plugin: https://github.com/Turnoutt/capacitor-firebase-dynamic-links

@karen1au, @marcocrodutti, and @ericgopak -

I had the same issue, to solve it I had to use the right way to work with URLs and query strings. Let me know if that helps.

const URLPARAMS = new URL(`https://myapp/invite`);
          URLPARAMS.searchParams.append('inviteTo', params.phoneNumber);
          URLPARAMS.searchParams.append('invitedId',this.user._id);
          URLPARAMS.searchParams.append('invitedbyGroupId', this.currentGroup._id);
          URLPARAMS.searchParams.append('invitedbyEmail', params.email);

createShortDynamicLink({
          domainUriPrefix: "https://myapp.page.link",
          link: URLPARAMS.href,
          .....

@ericgopak I'm trying with the capacitor plugin but it's giving me the same error

7.0.0 - [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://xxx";
    link = "https://xxx";
}

code inside this never get executed...

CapacitorFirebaseDynamicLinks.addListener('deepLinkOpen', (data) => doing something)

@nuno thanks for your solution! But i'm using firebase generated link for authentication so I don't really have control in constructing the link :(

[marcocrodutti]

Thank you @nuno.
Like @karen1au I am trying to open a generated link.

I can add a detail: we are using React. Is it the same for you @karen1au ?

[karen1au]

@marcocrodutti I'm using Vue, but it shouldn't matter?

[marcocrodutti]

You are right, sorry. It is not relevant.

For me, converting the manually constructed long dynamic link to a short dynamic link fixed this error (using latest DynamicLinks version 8.6.0)

okay this works only when the app is open already, not for a cold start. then it brings me to the main screen within my app (Edit: when cold starting, getDynamicLink() can be used to handle dynamic links on iOS)
