Workers Rate Limiting API not working



### What are the steps to reproduce the issue?
import { cloudflareRateLimiter } from "@hono-rate-limiter/cloudflare";

const app = new Hono();
const getClientIP = (c) => {
  return c.req.header("cf-connecting-ip") || 
         c.req.header("x-real-ip") ||
         c.req.header("x-forwarded-for")?.split(',')[0] ||
         c.req.raw.socket?.remoteAddress ||
         "unknown";
};


app.get("/api/search", 
  cloudflareRateLimiter({
    rateLimitBinding: (c) => c.env.SEARCH_RATE_LIMITER,
    keyGenerator: getClientIP,
  }),
  cache({ cacheName: 'search-cache', ttl: 3600 }), // Caching: 1 hour
  async (c) => {
    let query = decodeURIComponent(c.req.query('query') || '');
    
    if (query.length > 60) { // Input length restriction: max 50 characters
      c.status(400);
      return c.text("Query too long");
    }
}
);

            "limit": 20,
            "period": 60

it works if defined globally like this –
app.use(“/api/*”,
cloudflareRateLimiter({
rateLimitBinding: (c) => c.env.COMMENTS_RATE_LIMITER,
keyGenerator: (c) => c.req.header(“cf-connecting-ip”) ?? “”,
}),
);

but does not work if specific rate limiters are applied directly to the /api/posts/comments and /api/search endpoints…
