## Fija tu versión de `fastapi` { #pin-your-fastapi-version }

Lo primero que debes hacer es "fijar" la versión de **FastAPI** que estás usando a la versión específica más reciente que sabes que funciona correctamente para tu aplicación.

Уже сейчас вы можете создавать приложения в продакшене, используя **FastAPI** (и скорее всего так и делаете), главное убедиться в том, что вы используете версию, которая корректно работает с вашим кодом.

## Закрепите вашу версию `fastapi` { #pin-your-fastapi-version }

Первым делом вам следует "закрепить" конкретную последнюю используемую версию **FastAPI**, которая корректно работает с вашим приложением.

Например, в своём приложении вы используете версию `0.112.0`.

    the request already contains an `Accept` header.

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a

 *  Fix: Follow HTTP 307 and 308 redirects on methods other than GET and POST. We're reluctant to

	// clientPingInterval will ping the remote handler every 15 seconds.
	// Clients disconnect when we exceed 2 intervals.
	clientPingInterval = 15 * time.Second

	// Deadline for single (non-streaming) requests to complete.
