Returning JSON

[vorcigernix]

I am trying to follow example code from the readme. For some reason it returns

KvError::Serialization: expected value at line 1 column 1
panicked at 'KvError::Serialization: expected value at line 1 column 1', src/lib.rs:20:1

where error line is where I serialize object to json like
Some(jmeniny) => Response::from_json(&jmeniny.as_json::<Jmeniny>()?),
When I format the response as a string, it works fine:
Some(jmeniny) => Response::ok(&format!("response: {:?}", &jmeniny)),
results in
response: KvValue("Hynek")
It seems that from_json use serde internally, so it should work fine. Or I am overlooking something basic in KV.
Jmeniny struct is like this:

#[derive(Deserialize, Serialize)]
struct Jmeniny {
    name: String,
}

I think that it is some stupid mistake, but I'll appreciate any help.

So the get function on KV returns a worker_kv::KvValue struct, that implement as_json trait..which is where it probably fails?

Yes, it generally fails because the value structure I had in KV wasn't json. Now, reading docs again IDK how I missed it :)
