So, the frontend (that runs in the browser) would try to reach `/openapi.json` and wouldn't be able to get the OpenAPI schema.

Because we have a proxy with a path prefix of `/api/v1` for our app, the frontend needs to fetch the OpenAPI schema at `/api/v1/openapi.json`.

## Excluir parámetros de OpenAPI { #exclude-parameters-from-openapi }

Para excluir un parámetro de query del esquema de OpenAPI generado (y por lo tanto, de los sistemas de documentación automática), establece el parámetro `include_in_schema` de `Query` a `False`:
