Can't add custom routes to `labelerServer.app`

[mattbrailsford]

I'd like to add a custom route to the labelerServer.app instance such that I can respond to a webhook request to regenerate my label assignments, but whenever I try to add a route to the app, it just fails to start the labelerServer.

I've tried this as the most basic example

labelerServer.app.get("/my-custom-route", async (_req, res) => {
  // Logic should go here
  return res.send();
});

// Start the label server listener here

Should this be able to work? And am I doing something wrong?

Hmm, looks like a timeout resolves this. I guess the websocket connection needs to come first and then the registrations, but given I initialize the route straight after creating the labeler server instance it's not finished waiting on the promise so I seem to need to wait a few ms before I can register routes

Maybe it would be nice if we could pass a callback to the constructor to perform additional config?
