ios – Azure Communication Calling SDK crashes on begin name

I’m making an attempt to begin a one on one name utilizing Azure CommunicationCalling sdk. I get a crash inside one of many sdk features as proven in screenshot for backtrace beneath.

Code for begin name:-

func startCall(callee: String, successHandler: @escaping (Name?) -> Void ) {

    // begin name logic
    debugPrint(callee)
    let callees:[CommunicationIdentifier] = [createCommunicationIdentifier(fromRawId: callee)]
    debugPrint(callees)
    self.callAgent?.startCall(members: callees, choices: StartCallOptions()) { (name, error) in
        if let error = error {
            debugPrint(error.localizedDescription)
            successHandler(nil)
        } else {
            self.name = name
            debugPrint("name positioned efficiently")
            successHandler(name)
        }
    }
}

I’ve verified that decision agent and communication identifier arr obj handed will not be nil.

Crash log:-
*** Terminating app as a consequence of uncaught exception ‘NSInvalidArgumentException’, cause: ‘*** -[__NSArrayM insertObject:atIndex:]: object can’t be nil’
terminating with uncaught exception of kind NSException
