     * implementations (nghttp2) forbid peers from taking advantage of settings before they have
     * acknowledged! In particular, we shouldn't send frames that assume a new `initialWindowSize`
     * until we send the frame that acknowledges this new size.

### No Return Type { #no-return-type }

You can also omit the return type. FastAPI will use the [`jsonable_encoder`](./encoder.md) to convert the data and send it.
