Describe the bug
WebSocket adapter returns 500 without any error. I couldn't find what is causing the error as the error message is swallowed for $connect route.

To Reproduce


    handler: src/manage-connection.handler
      - websocket:
          route: $connect

handler code:

const laconia = require("@laconia/core");
const adapterApi = require("@laconia/adapter-api");

const app = async () => {};
const webSocket = adapterApi.webSocket();

exports.handler = laconia(webSocket(app));

Expected behavior

  1. Return 200 as $connect is a happy path
  2. Error message should be surfaced to the user

Actual behavior

  1. Return 500
  2. Error message is swallowed, I needed to go to createWebSocketAdapter.js and put a console.log inside catch block

The error message:
