How do I get the error of Option extractor

[juchiast]

I'm using Option to have and optional request body

    params: Option<web::Json<Params>>,

however, when an invalid request is received, actix-web ignore the error, only printing it in DEBUG

DEBUG actix_web::extract: Error for Option<T> extractor: Json deserialize error: invalid value: ....

How do I make actix-web return an error in this case?

Use actix_web::Result<T> (or Result<T, E>) instead of Option<T> as the extractor.
