Formatting validation errors

[emrosenf]

I realize the validation errors are coming from Schema, but is there any way to further customize or improve upon this?

const LoginBody = S.Struct({
  name: S.String,
  password: S.String.pipe(S.minLength(5, { 
    message: () => 'My custom message'
  }))
})

Error message:

{
    "error": "Request validation error",
    "location": "body",
    "message": "{ readonly name: string; readonly password: a string at least 5 character(s) long }\n└─ [\"password\"]\n   └─ My custom message"
}

Preferred:

{
    "error": "Request validation error",
    "location": "body",
    "message": {
         "password": "My custom message"
    }
}

The logic that I want is mostly implemented In the react-hook-form/resolvers effect logic

One way to allow this is if ServerRequestParser could be a service that I could implement and then provide?

Or perhaps better: an ErrorFormatter service or function?

The Schema error message is great for a programmer, but that's not a shippable error message for a public API

I used to have a pluggable schema error formatter in the past but I got rid of it. I'll take a look and possibly reintroduce it.
