Client request response parse error

[boyswan]

Every RPC request is failing with
ParseError(Error("data did not match any variant of untagged enum Id", line: 1, column: 47))

Example:

let client = HttpClientBuilder::default()
    .build("https://kusama-rpc.polkadot.io:443")
    .unwrap();
let response: String = client.request("system_chain", None).await.unwrap();
// fails

The data is being returned in the actual response:
Ok(Object({"jsonrpc": String("2.0"), "result": String("Development"), "id": Number(0)}))

Hey @boyswan

That should work, have you enabled --feature arbitrary-precision on serde_json by any chance?
See #480 for futher info
