    /**

     * @param path
     *            The path to the properties file. If {@code null}, a {@link FileAccessException} is thrown.

     *             If the file cannot be accessed or created.

And then, that system (in this case **FastAPI**) will take care of doing whatever is needed to provide your code with those needed dependencies ("inject" the dependencies).

This is very useful when you need to:

* Have shared logic (the same code logic again and again).

* O item que o cliente está tentando acessar não existe.
* etc.


Nesses casos, você normalmente retornaria um **HTTP status code** próximo ao status code na faixa do status code **400** (do 400 ao 499).

Isso é bastante similar ao caso do HTTP status code 200 (do 200 ao 299). Esses "200" status codes significam que, de algum modo, houve sucesso na requisição.

Lo que normalmente hago es crear un directorio llamado `code` dentro de mi directorio de usuario.

Y dentro de eso creo un directorio por proyecto.

<div class="termy">

```console
// Ve al directorio principal
$ cd
// Crea un directorio para todos tus proyectos de código
$ mkdir code
// Entra en ese directorio de código
$ cd code
// Crea un directorio para este proyecto
$ mkdir awesome-project

O que normalmente faço é criar um diretório chamado `code` dentro do meu diretório home/user.

E dentro disso eu crio um diretório por projeto.

<div class="termy">

```console
// Vá para o diretório inicial
$ cd
// Crie um diretório para todos os seus projetos de código
$ mkdir code
// Entre nesse diretório de código
$ cd code
// Crie um diretório para este projeto
$ mkdir awesome-project
