Please describe the bug

In sample k.direct-line-token, the javascript web and bot project server routes and handlers were not functioning as expected, causing issues with server startup and request handling.

Environment:

npm 8.19.4
node v16.20.1

Do you see any errors in console log?

# npm start

> web@1.0.0 start
> node-dev --no-notify --respawn .

AssertionError [ERR_ASSERTION]: Handler [handler-1 on POST /api/messages] is missing a third argument (the "next" callback) but is not an async function. Middleware handlers can be either as
ync/await or callback-based.Callback-based (non-async) handlers should accept three arguments: (req, res, next). Async handler functions should accept maximum of 2 arguments: (req, res).

How to reproduce the issue?

This issue reproduces in both javascript/web and javascript/bot in sample sample k.direct-line-token:

javascript/web

Navigate to the root javascript/web project directory.
Run npm i then npm start to start the server.
Send a request to the /api/messages route.
Observe the error related to the missing third parameter in the handler function.

javascript/bot

Navigate to the root javascript/bot project directory.
Run npm i then npm start to start the server.
Send a request to the /api/messages route.
Observe the error related to the missing third parameter in the handler function.

What do you expect?

Requests to the /api/messages route should be handled without errors.

What actually happened?

Received an error indicating the missing third parameter (next callback) in the handler function for the following files:

javascript/bot: createBot.js.
javascript/web: botMessages.js.

Do you have any screenshots or recordings to repro the issue?

Additional context

This issue pertains to how Restify expects handler functions to be structured. The function should either be an async function with (req, res) or a callback-based function with (req, res, next).
