Do mesmo modo, você pode sobreescrever o `HTTPException`.

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:

```Python hl_lines="3-4  9-11  22"
{!../../docs_src/handling_errors/tutorial004.py!}
```

/// note | "Detalhes Técnicos"

    protected final ColumnInfo _columnDescription = cci("description", "description", null, null, String.class, "description", null, false,
            false, false, "text", 0, 0, null, null, false, null, null, null, null, null, false);
    protected final ColumnInfo _columnHandlerName = cci("handlerName", "handlerName", null, null, String.class, "handlerName", null, false,

//// tab | `fastapi`

If you use the `fastapi` command:

<div class="termy">

```console
$ <pre> <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:single">main.py</u>

    server.enqueue(MockResponse(body = "a"))
    server.enqueue(MockResponse(body = "b"))
    val request =
      Request(
        url = server.url("/"),
        body = "request body".toRequestBody("text/plain".toMediaType()),
      )
    assertConnectionReused(request, request)
  }

  @Test
  fun connectionsAreReusedWithHttp2() {
    enableHttp2()
    server.enqueue(MockResponse(body = "a"))
