jetton content metadata

hello. thank u for this tutorial.
I have a issue when deploy the jettonContentMetadata not set in tonScan, why?

this line:
   const jettonParams = {
        name: "test USDT",
        description: "This is description for test USDT",
        symbol: "testUSDT",
        image: "https://i.ibb.co/J3rk47X/USDT-ocean.webp"
    };
