    * Add new `root_path` parameter for `FastAPI` applications to provide it in cases where it can be set with the command line (e.g. for Uvicorn and Hypercorn, with the parameter `--root-path`).
    * Deprecate `openapi_prefix` parameter in favor of the new `root_path` parameter.

Open your browser at [http://127.0.0.1:8000](http://127.0.0.1:8000).

There you can set:

* The "Item ID", used in the path.
* The "Token" used as a query parameter.

/// tip

Notice that the query `token` will be handled by a dependency.

///

With that you can connect the WebSocket and then send and receive messages:

    /*
     * uncheckedCastNullableTToT is safe as long as the callers are careful to pass a "real" T
     * whenever they pass `true` for the matching `has*Bound` parameter.
     */
    if (hasLowerBound) {
      int unused =
          comparator.compare(
              uncheckedCastNullableTToT(lowerEndpoint), uncheckedCastNullableTToT(lowerEndpoint));
    }

For example, here it is using the first tag (you will probably have only one tag) and the *path operation* name (the function name).

You can then pass that custom function to **FastAPI** as the `generate_unique_id_function` parameter:
