# Devolver una respuesta directamente

Cuando creas una *operación de path* normalmente puedes devolver cualquier dato: un `dict`, una `list`, un modelo Pydantic, un modelo de base de datos, etc.

Por defecto, **FastAPI** convertiría automáticamente ese valor devuelto a JSON usando el `jsonable_encoder` explicado en [Codificador Compatible JSON](../tutorial/encoder.md){.internal-link target=_blank}.

                include "**/*.xml"
                include "*.xsl"
            }
            from(archives.zipTree(getDocbookStylesheets().singleFile)) {
                eachFile {
                    fcd -> fcd.path = fcd.path.replaceFirst("^docbook", "")
                }
            }
            into(getTemporaryDir())
        }

        def stylesheetFile = new File(getTemporaryDir(), "dslHtml.xsl")

    boolean generate(String thumbnailId, File outputFile);

    boolean isTarget(Map<String, Object> docMap);

    boolean isAvailable();

    void destroy();

    Tuple3<String, String, String> createTask(String path, Map<String, Object> docMap);

    assertThat(response.trailers()).isEmpty()
  }

  @Test
  fun testFailsIfTrailersNotSet() {
    val response =
      newResponse("".toResponseBody()) {
        // All live paths (Http1, Http2) in OkHttp do this
        trailers { error("trailers not available") }
      }

    assertFailsWith<IllegalStateException>(message = "trailers not available") {
      response.trailers()
