Deep Linking Fails with Empty Referring Parameters

[metinjakupi]

Describe the bug

  BranchDeepLinks.addListener('init', (event: BranchInitEvent) => {
        alert(JSON.stringify(event.referringParams))

     //referringParams are empty
   })

here is how i generate a shortUrl that contains token

  async generateBranchLink() {
    try {
      let user = await this.storageService.get('user');

      var properties = {
        $match_duration: 2000,
        custom_string: 'data',
        custom_boolean: true,
        $custom_data: JSON.stringify({token: user.share_token}),
      };

      let res = await BranchDeepLinks.generateShortUrl({properties});
      return res.url;
    } catch (err) {
      console.error('Error generating Branch link:', err);
      throw err;
    }
  }

Steps to reproduce

1.Implement capacitor-branch-deep-links as per the documentation 2.Generate a deep link with custom user share token 3.Attempt to open the app through the generated deep link.

Expected behavior

The app opens via the deep link, but all parameters that were appended to the deep link URL are received as empty. This behavior is consistent across different devices and platforms.

@metinjakupi have you found solution?

[metinjakupi]

@qliqdev It worked once only, but now it stopped again so i dont know what

[echo-branch]

@metinjakupi Could you open a support ticket for this? https://help.branch.io/using-branch/page/submit-a-ticket

The github issues page has much longer response times than support tickets.

For this particular issue, I suspect there is a configuration issue with the entitlements file. The one time success could have been due to a deferred deeplink rather than correct Universal Link setup.

[raghudantuluri]

For us everything was working fine including deferred deep links using IOS Native Solution until IOS15 but deferred deep linking broke since IOS 16, seeing similar issue, during App install we can see from branch debug log that link is coming through but in the branch init listener which starts listening after App install, referringParams are coming empty

[raghudantuluri]

If I disable Private Relay in my iPhone(iOS 17) , I am getting this allow paste prompt, and after hitting allow deferred deep link is working.

however as per below two blogs from branch, this should have been supported and deferred deep link should work without having to disable private relay?

https://www.branch.io/resources/blog/everything-you-need-to-know-about-ios-16-and-pasteboard-opt-ins/

Here is what we have from podlock and logs PODS:

• BranchSDK (3.4.3)
• Capacitor (5.7.2):
  • CapacitorCordova
• CapacitorApp (5.0.7):
  • Capacitor
• CapacitorBranchDeepLinks (7.1.0):
  • BranchSDK
  • Capacitor

And these are the logs I see related to branch from Xcode, still not getting referringparams after install
