I'm having an error when trying to parse JSON with rocket. This is my code:
extern crate serde;
use rocket::serde::{json::Json, Deserialize};
use serde::Serialize;
#[macro_use]
extern crate rocket;
mod eth;
mod rocket_test;
#[launch]
fn rocket() -> _ {
rocket::build().mount("/task", routes![body])
}
#[derive(Serialize, Deserialize)]
struct Message2 {
id: usize,
}
#[post("/", format = "json", data = "<message>")]
async fn body(message: Json<Message2>) -> &'static str {
"Fine"
}
And this is my toml file:
[dependencies]
serde = {version = "1.0", features = ["derive"]}
serde_derive = "1.0"
serde_json = "1.0"
tester = "0.9.0"
tokio = {version = "1", features = ["full"]}
[dependencies.rocket]
features = ["json"]
version = "0.5.0-rc.1"
I'm getting this error

It's just the same as in the example of JSON parsing. But I have no idea what is going wrong. I'm sending requests with VSCode Rest client just like this
POST http://127.0.0.1:8000/task
content-type: application/json
{
"id": 10
}
It looks like version 1.16.0 of tokio has an error: https://github.com/tokio-rs/tokio/issues/4435
Do a cargo update and it should update your dependency to 1.16.1.
