hi @prashanthsridhar - thanks for opening the issue. we'll do some investigation on our end and report back.

I believe this is correct behavior.

We have 2 modes in Direct Line: (short) polling and Web Socket.

Looks like you are connected via our polling mechanism, thus, there will be a poll call every second.

When you call createDirectLine, if you did not set webSocket: false explicitly, it should start as a Web Socket connection.

p.s. Direct Line does not support long polling.
