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`revoked()` and any future calls to the context will result in a `TypeError: Cannot perform * 'set' on a proxy that has been revoked` being thrown.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 Note: If you see the error `TypeError: Cannot perform 'set' on a proxy that has been revoked` * 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.
