can anyone help me?

I'm new to rust and
I'am facing error in post request.
axum 7

type MySchema = Schema<QueryRoot, Mutation, EmptySubscription>;
async fn graphql_handler(
schema: State,
_headers: HeaderMap,
request: GraphQLRequest,
) -> GraphQLResponse {
schema.execute(request.0).await.into()
}

let app = Router::new()
.route("/api/healthchecker", post(health_checker_handler))
.route("/graphql", post(graphql_handler))
.route("/playground", get(graphql_playground))
.with_state(schema.clone())
.layer(
CorsLayer::new()
.allow_origin("http://localhost:3000".parse::().unwrap())
.allow_methods([Method::GET, Method::POST, Method::PATCH, Method::DELETE]),
);

and the error here
the trait bound fn(axum::extract::State<async_graphql::Schema<QueryRoot, schema::Mutation, EmptySubscription>>, HeaderMap, GraphQLRequest) -> impl std::future::Future<Output = GraphQLResponse> {graphql_handler}: Handler<_, _> is not satisfied

= help: the following other types implement trait Handler<T, S>:
<Layered<L, H, T, S> as Handler<T, S>>
<MethodRouter as Handler<(), S>>
