*

* activity. This reference can be stored in a database and used to resume the conversation at a later time.
* The reference can be created from any incoming activity using `TurnContext.getConversationReference(context.activity)`.
*
* The processing steps for this method are very similar to [processActivity()](#processactivity)
* in that a `TurnContext` will be created which is then routed through the adapters middleware
* before calling the passed in logic handler. The key difference is that since an activity
* wasn't actually received from outside, it has to be created by the bot. The created activity will have its address
* related fields populated but will have a `context.activity.type === undefined`.

/**
* Processes an incoming request received by the bots web server into a TurnContext.
*
* @remarks
* This method is the main way a bot receives incoming messages.
*
* This method takes a raw incoming request object from a webserver and processes it into a
* normalized TurnContext that can be used by the bot. This includes any messages sent from a
* user and is the method that drives what is often referred to as the bot's "Reactive Messaging"
* flow.
*
* The following steps will be taken to process the activity:
*
* - The identity of the sender will be verified to be either the Emulator or a valid Microsoft
* server. The bots `appId` and `appPassword` will be used during this process and the request
* will be rejected if the senders identity can't be verified.
* - The activity will be parsed from the body of the incoming request. An error will be returned
* if the activity can't be parsed.
* - A `TurnContext` instance will be created for the received activity and wrapped with a
* [Revocable Proxy](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy/revocable).
* - The context will be routed through any middleware registered with the adapter using
* [use()](#use). Middleware is executed in the order in which it's added and any middleware
* can intercept or prevent further routing of the context by simply not calling the passed
* in `next()` function. This is called the "Leading Edge" of the request; middleware will
* get a second chance to run on the "Trailing Edge" of the request after the bots logic has run.
* - Assuming the context hasn't been intercepted by a piece of middleware, the context will be
* passed to the logic handler passed in. The bot may perform additional routing or
* processing at this time. Returning a promise (or providing an `async` handler) will cause the
* adapter to wait for any asynchronous operations to complete.
* - Once the bot's logic completes, the promise chain set up by the middleware stack will be resolved,
* giving middleware a second chance to run on the "Trailing Edge" of the request.
* - After the middleware stack's promise chain has been fully resolved the context object will be
* `revoked()` and any future calls to the context will result in a `TypeError: Cannot perform
* 'set' on a proxy that has been revoked` being thrown.
*
* > [!TIP]
* > Note: If you see the error `TypeError: Cannot perform 'set' on a proxy that has been revoked`
* > appearing in your bot's console output, the likely cause is that an async function was used
* > without using the `await` keyword. Make sure all async functions use await!
*
* ```JavaScript
* server.post('/api/messages', (req, res) => {
* // Route received request to adapter for processing
* adapter.processActivity(req, res, async (context) => {
* // Process any messages received
* if (context.activity.type === ActivityTypes.Message) {
* await context.sendActivity(`Hello World`);
* }
* });
* });
* ```
* @param req An Express or Restify style Request object.
* @param res An Express or Restify style Response object.
* @param logic A function handler that will be called to perform the bots logic after the received activity has been pre-processed by the adapter and routed through any middleware for processing.

*
* Instead of calling these methods directly on the adapter, calling `TurnContext.sendActivities()` or `TurnContext.sendActivity()`
* is the preferred way of sending activities as that will ensure that outgoing activities have been properly addressed
* and that any interested middleware has been notified.
