[ashishpatill]

Describe the bug I am trying to start a one on one call using Azure CommunicationCalling sdk for iOS. I am getting a crash inside one of the sdk functions as shown in screenshot for backtrace below.

Exception or Stack Trace Exception:- *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil' terminating with uncaught exception of type NSException

Stack Trace:- Thread#0 0x00000001d70a6248 in __exceptionPreprocess () #1 0x00000001d0473a68 in objc_exception_throw () #2 0x00000001d724a6d4 in _CFThrowFormattedException () #3 0x00000001d72475cc in -[__NSArrayM insertObject:atIndex:].cold.1 () #4 0x00000001d70b0350 in -[__NSArrayM insertObject:atIndex:] () #5 0x000000010699cfe4 in -[ACSIdentifiers toMRIs:] () #6 0x000000010697b044 in -[ACSCallAgent startCall:options:withCompletionHandler:] () #7 0x0000000102500648 in CallManager.startCall(callee:successHandler:)

I have verified that call agent and communication identifier arr obj passed is not nil.

func startCall(callee: String, successHandler: @escaping (Call?) -> Void ) {
    // start call logic
    debugPrint(callee)
    let callees:[CommunicationIdentifier] = [CommunicationUserIdentifier(callee)]
    debugPrint(callees)
    self.callAgent?.startCall(participants: callees, options: StartCallOptions()) { (call, error) in
        if let error = error {
            debugPrint(error.localizedDescription)
            successHandler(nil)
        } else {
            self.call = call
            debugPrint("call placed successfully")
            successHandler(call)
        }
    }
}
