how to use rate limit api

[kleedodo]

I ran into a problem when I tried to use the rate limit api, this is my code:

use worker::{event, Context, Env, RateLimiter, Request, Response, Result};

#[event(fetch)]
async fn fetch(_req: Request, env: Env, _ctx: Context) -> Result<Response> {
    console_error_panic_hook::set_once();
    let api_rate_limit = env.get_binding::<RateLimiter>("API_RATE_LIMIT")?;
    let res = api_rate_limit.limit("111".to_string()).await?;
    if res.success {
        return Response::ok("Hello World!");
    }
    Response::error("too many request", 429)
}

and wrangler.toml:

name = "testworker"
main = "build/worker/shim.mjs"
compatibility_date = "2025-01-14"

[[unsafe.bindings]]
name = "API_RATE_LIMIT"
type = "ratelimit"
namespace_id = "666"
simple = { limit = 10, period = 10 }

[build]
command = "cargo install -q worker-build && worker-build --release"

When I run the code and prepare to try to access, I get the error:

[wrangler:inf] GET / 500 Internal Server Error (2ms)
✘ [ERROR] Binding cannot be cast to the type RateLimiter from Ratelimit

Is the way I'm using the API incorrect? How to use rate limit api? please help…
