App crash on calling Voice.connect() #94

Closed sgowda97 closed 1 year ago

sgowda97 commented 2 years ago

Description

App is crashing as soon as I place an audio call.

Steps to Reproduce

  1. Place a call using Voice.connect()

Code

func performVoiceCall(uuid: UUID, client: String?, completionHandler: @escaping (Bool) -> Swift.Void) {
        guard let token = accessToken else {
            completionHandler(false)
            return
        }

        let connectOptions: ConnectOptions = ConnectOptions(accessToken: token) { (builder) in
            for (key, value) in self.callArgs {
                builder.params[key] = "\(value)"
            }

            builder.uuid = uuid
        }
        let theCall = TwilioVoiceSDK.connect(options: connectOptions, delegate: self)
        self.call = theCall
        self.callKitCompletionCallback = completionHandler
    }

Expected Behavior

Outgoing call should happen without crashing.

Actual Behavior

Crashes after a few seconds of calling Voice.connect(), the TwiML end-point is not being called either.

Hi @sgowda97

From the stack you provided, I couldn't find the exact reason that caused the crash in thread 1. Is this reproducible in the debugging environment and did you see the system message when it crashed?

Hi @bobiechen-twilio,
