Problem with app state

[bajrangCoder]

Summary

I'm in the process of creating a server using Axum, and I need to manage its state. I looked at some examples and tried to implement it, but whenever I use State in the parameter of a post endpoint, it starts breaking, and I'm not sure why. I'm struggling to figure out how to fix it and what might be causing the issue.

My code can be found here.

Error log:

error[E0277]: the trait bound `fn(Json<TerminalDimension>, State<AppState>) -> impl Future<Output = Result<impl IntoResponse, AppError>> {create_term_handler}: Handler<_, _>` is not satisfied
