Confusing about the escaped chars in String of InputValue

[UkonnRa]

Because now juniper does not support JSON scalar(#509), I have to pass a JSON Object using a piece of string, like:

let (res, errors) = juniper::execute_async(
      r#"mutation {
createUser(input: {
    nickname: "nickname",
    avatar: "http://example.com", 
    badges: "{\"Github\": \"https://github.com\"}"}) {
        id
        nickname
    }
}"#,
    None,
    &schema,
    &Variables::new(),
     &ctx,
).await.unwrap();

And then I created a new Scalar type named JsonValue:

juniper::graphql_scalar!(JsonValue where Scalar = <S> {
    // other definitions...
    from_input_value(v: &InputValue) -> Option<JsonValue> {
        v.as_string_value().and_then(|s| {
            println!("input string: {:?}", s);
            serde_json::from_str(s).ok()
        })
    }
}

What I want is receiving a string like: {"Github": "https://github.com"}, but in fact, I get:

{\"Github\": \"https://github.com\"}

I wonder if this a feature? How can I pass the string from input object correctly?

You appear to be using Rust raw string literals (r#...#) which means you do not need to escape " on the Rust side. See https://rahul-thakoor.github.io/rust-raw-string-literals/.

Do you still see the resulting slashes if you remove them from the Rust side? If so please reopen!
