Getting exception in ProcessKeepAlive (v2 ListenWebSocketClient) #390
Description
What is the current behavior?
Just switched from C# client 4.3.6 to 6.6.0 and I'm seeing an exception get logged from ProcessKeepAlive:
ProcessKeepAlive: System.NullReferenceException thrown Object reference not set to an instance of an object.
The exception is caught by the Deepgram client and is sent to the logger, so it shows up in the application logs.
Steps to reproduce
This appears to happen after the ListenWebSocketClient is closed, via SendClose().
Expected behavior
No error logged when closing the client.
