AWSIoT crash - [AWSIoTMQTTClient webSocketDidOpen:] + 1228 (AWSIoTMQTTClient.m:1228) #5180

Closed jonduenas closed 8 months ago

Describe the bug Our iOS app currently has 2 crash reports in the past couple weeks from the webSocketDidOpen at line 1228 of AWSIoTMQTTClient.m file.

To Reproduce It's unclear at this point. From what I can tell it looks like they're opening the app after having previously used it the day before. I've tried reproducing this locally by putting the app in the background for several minutes and bring the app back, both with good network and poor network conditions, and can't seem to reproduce it myself.

Hello, Thank you for posting this. Do you have verbose logs leading up to the stack trace which can help us debug further? Make sure to remove any sensitive information.

jonduenas commented 9 months ago

Unfortunately we don't have detailed logging accessible from the devices that crashed. And since I can't seem to reproduce myself locally, I don't have any that way either. I realize this isn't a lot of info to go off of, but hoped it might be helpful anyways. Or, if there was any insight whether there is anything on our end we can do to address this or mitigate it.

@jonduenas could you please share the full crash report? There's additional information that might be helpful for us.

Thanks!
