🐛 [Firebase Dynamic Link] Dynamic link is not opening on iOS platform but working fine on Android

[harshsoniaubergine]

Bug report

Describe the bug
We have implemented a firebase dynamic link for the project. It works fine with the Android platform but not with iOS.
We saw that the iOS app is opening on tap of the link but it doesn't give us the link or callback on the app.

Any help is appreciated!

Additional context

We have tried following things so far

• App is opening but initialLink is coming up null and onLink is not called
• Tried running the app in release mode, still it is not working
• We tried upgrading the dependencies to the latest version
• We ran the diagnostic tool as well and received the following error message

Firebase Dynamic Links framework version 10.3.0 System information: OS iOS, OS version 16.2, model iPhone Current date 2022-12-13 21:05:16 +0000 Device locale en-US (raw en_US), timezone America/Chicago ERROR: Specified custom URL scheme is (null) but Info.plist do not contain such scheme in CFBundleURLTypes key. AppID Prefix: AN68337YX5, Team ID: AN68337YX5, AppId Prefix equal to Team ID: YES performDiagnostic detected 1 ERRORS. ---- Firebase Dynamic Links diagnostic output end ----

• To resolve the above diagnostic we checked everything that was suggested on other Github issues: Verified dynamic link setup, and associated domains on the URL.

Here are some snaps for the setup

Same issue

[darshankawar]

Thanks for the report @harshsoniaubergine
Looking at the error you posted:

Specified custom URL scheme is (null) but Info.plist do not contain such scheme in CFBundleURLTypes key indicates there's something wrong with the link / url itself.

Usually, the error should have identified the url scheme as below for example:

Specified custom URL scheme is com.*******.**** , but in your case, it is being rendered as null, that means it is unable to find the url scheme. So Please try to debug and confirm if the link parameter is correct is generated properly.

[harshsoniaubergine]

I checked. The link parameter is correctly generated and the same link is working fine on Android as well.

Let me know if I have misunderstood your comment here.

[darshankawar]

@harshsoniaubergine Thanks for the update.
Is there a way for you to provide a minimal code sample that we can use and run to verify this ?

Alternatively, you may also check the plugin example and see if using it integrated with your local firebase setup, do you still get same behavior or not.

Hey @harshsoniaubergine. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[google-oss-bot]

Since there haven't been any recent updates here, I am going to close this issue.

@harshsoniaubergine if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
