production build warning when implementing Websocket

[miguelopezv]

I'm implementing a websocket on my Gatsby site (I'm using Websocket-Node package, socket.io is not an option), it works but when I ran the build command I get the following warning

warn WebpackError: Unsafe builtin usage fs.readdirSync

and this one below

256 |         self._req = null;

is there a way to get rid of this warnings?
