Websocket client is being destroyed

client.subDepth(symbol, "step5", [](Depth depth) {
	cout << "subDepth" << endl;
	cout << depth.ts << endl;
	cout << depth.asks[0].price << endl;
  });

After running for 3-4 minutes, the code captures an exception: "Websocket client is being destroyed" in Lines 39-43.

writer.String(to_string(pong).c_str());

I think the pong message should contain a long value, not a string?
Any ideas?
