Hi @ashishp-dev !

Could you please provide more context regarding the error? Specifically, what operation are you trying to perform (e.g. publish/receive a message), and which lines of code are causing the app to crash? Additionally, could you let me know what version of ably-flutter you are using?

Thank you!

[ashishp-dev]

[ashishp-dev]

@VeskeR Any update??

[ttypic]

Hey @ashishp-dev,

We are still trying to reproduce the issue on our end. To help us understand the exact point at which the error occurs, could you please enable verbose logging and add the logs to the issue report? This would assist us in diagnosing the problem. Additionally, could you let us know if the issue only occurs on a physical device, or if it can be reproduced on an emulator as well?

[ashishp-dev]

Yes this is happening on the physical device of iPhone 7 plus. Not happening on the simulator.
I am sharing more information

[ashishp-dev]

@VeskeR @ttypic Any update??

[ttypic]

Hey @ashishp-dev,

We still can't reproduce the issue. Could you please share the version of Flutter you are using? Please note that the latest version of Flutter officially supports only iOS 17. Could you also check our example app from this repository? Could you reproduce the issue with it?

[ashishp-dev]

@ttypic i am using this flutter version (3.22.1)

[ashishp-dev]

@ttypic @VeskeR

Issue is resolved now when i write client options something like this.

final clientOptions = ably.ClientOptions(
    key: ApiConstant.ABLY_KEY,
    transportParams: {
      'remainPresentFor': remainPresentFor,
      'heartbeatInterval': heartbeatInterval
    },
    clientId: userID,
    logLevel: ably.LogLevel.verbose,
  );

  var realtime = ably.Realtime(key: ApiConstant.ABLY_KEY);
  realtime.options = clientOptions;

when i write like this my iphone 7 is crashing
var realtime = ably.Realtime(key: ApiConstant.ABLY_KEY, options: clientOptions);

[ttypic]

Thank you for sharing this @ashishp-dev. Now I got it,

ably.Realtime(key: ApiConstant.ABLY_KEY, options: clientOptions);

You can't use it like this. You should specify either key or options, not both. If you specify both arguments, key will be ignored. Additionally, if you don't specify key or other authentication parameters inside your ClientOptions, it will fail.

Thank you once again for spotting this. We will throw an explicit exception in this case.

[ashishp-dev]

Still app is crashing, I identify the what is the main crash issue. When i write something like this that i am facing the crash

transportParams: {
      'remainPresentFor':'5000',
      'heartbeatInterval': '5000'
    },

without transportParams param my app is not crashing it is working fine. But my issue is we need this parameters as on our Backend system this is depending to go further. So i am not allowing to remove this transportParams . So can you please look into this at high priority.
This crash issue is happen on some of the iPhone devices, like 7 plus with iOS running 15.x.x , second is iPhone 12 with iOS 16.5 running (almost latest OS) so we are struck for our release due to this. I urge you to check ASAP and give proper solution to come-out from this situation

[ttypic]

@ashishp-dev, we’ve found a potential problem related to the transportParams configuration and are working on it as a top priority. We'll keep you updated on our progress and aim to have a fix soon.

[ttypic]

@ashishp-dev We've published a new version (1.2.33) that should solve the issue. If the issue still exists, please feel free to reopen the ticket

[ashishp-dev]

Hey @ttypic

My crash problem is fixed now, this will help to lots of IOS crash
If i will face any issues then i will contact to you

Thank you!
