Lost connection to device - when authorizing Reader SDK #45

tonydiaz · 2020-05-18T13:21:54Z

Describe the issue

I'm seeing the reader-sdk-flutter-plugin/example project is losing connection to physical iPhone device as I authorize the Read SDK.

I'm running an iPhone 8 with iOS 13.3.1. Update: I updated to 13.4.1, same result.

There isn't a good trace on the error just loses the connection at the end.

Error log details:

To Reproduce

Steps to reproduce the issue.

Start project
Authorize the Microphone and Location permissions
Go to square developer site and generate mobile auth code in production
Given permission to use the camera on the app.
Use app to scan the QR code and then app crashes on the physical device (Lost connection to device.)

You can use the example project to reproduce the issue. I'm having the same problem on my project

  void authorize(String authCode) async {
    try {
      setState(() {
        _isLoading = true;
      });
      print('AuthCode: $authCode');
      var location = await 
            ReaderSdk.authorize(authCode); // ReaderSdk.authorize loses connection to device
      print('Location: $location'); //Never gets to this print statement
    } on ReaderSdkException catch (e) {
      ...
    } finally {
      setState(() {
        _isLoading = false;
      });
    }
  }

Expected behavior

The app should not crash when authorizing the SDK.

This works fine on the iPhone emulator. I wanted to test the physical card readers ao I need to run it on a physical device.

I believe this is related to the In-App Payments SDK same issue: square/in-app-payments-flutter-plugin#82 which is basically due to breaking changes from Flutter 1.12 >. I believe you need to use an older version of Flutter for this to work.

tonydiaz · 2020-05-19T13:10:07Z

Downgrading the flutter version is tough since that cascades to downgrading other packages that don't work on < 1.12 version of flutter.

Is there any other workaround to test out the functionality?

Looks like from the other issues there is no ETA on developing a fix?

StephenJosey · 2020-05-19T20:42:48Z

Unfortunately I'm not aware of a workaround, nor do I have an ETA on updating this.

I'm seeing the issue on Flutter version 1.11.0 as well using the example project in this repo using a physical device

The application loads. I tried scanning the QR for the Mobile Auth Code and entering it manually the app crashes for both ways. After the crash the app only loads the image below and crashes again.

@StephenJosey @okenshields Is there a way I can trace the problem better? Hard to figure out the root cause when the error is only Lost connection to device

StephenJosey · 2020-06-02T21:19:42Z

Apologies for the delay here, I will escalate to the team and follow up once I have more information.

tonydiaz · 2020-06-13T01:55:11Z

After some updates, I'm not no longer seeing this problem in my application. I'm not sure of any significant change I made that resolved it but I no longer have the disconnection.

I did implement an endpoint for the Mobile auth

I ran the example app again and used the camera to scan the QR Mobile Auth Code in the developer console. It lost the connection again. I wonder if there is something different with the auth code generated in the developer console versus the Mobile Auth API?

Not sure if you want me to close the issue. It would be nice if it is possible to have a stack trace error when a connection is lost.

Hi @tonydiaz,

Do you know if this happens when running on a physical android device as well? We recently did upgrade our plugins to Flutter 1.12+. Unfortunately I don't have a physical iPhone accessible to test it out.

tonydiaz · 2020-07-08T18:32:15Z

@mohsin-sq This only happened to me on a physical device. I only tried it on an iPhone.

I never had an issue with the android and iOS emulators.

My application now works but running the example project in the repo on my physical device still loses connection.

mohsin-sq · 2020-07-15T17:20:36Z

This ended up just being an issue with the example application. Some information in the info.plist was missing that is required for running on a physical device. After it was added, the application worked. Thanks for bringing this to our attention @tonydiaz ! Closing the issue, please feel free to reopen if you have any more questions regarding this.
