Have callback issue in Base Sepolia wih Entropy

Make sure to check the Pyth Documentation to check for guides, common errors and reference materials.

I’m not exactly sure what I did; I was just trying to ‘vibecode’ an idea I had. However, Gemini and Claude can’t seem to solve this callback issue. I’ve been experimenting with different smart contracts, but I can’t find a fix for this specific problem. I even asked the AI to generate the code along with all the documentation, but the issue persists

function entropyCallback(

    uint64 sequenceNumber,

    address provider,

    bytes32 randomNumber

) external {

    // ПЕРЕВІРКА БЕЗПЕКИ: Тільки контракт Entropy може це викликати

    require(msg.sender == ENTROPY_ADDRESS, "Scam attempt: Only Entropy allowed");

    

    // ПЕРЕВІРКА ПРОВАЙДЕРА: Тільки наш провайдер

    require(provider == PROVIDER_ADDRESS, "Wrong provider");



    // ✅ УСПІХ: Віддаємо число вашому сайту

    emit FlipResult(sequenceNumber, uint256(randomNumber));

}



// Функція, щоб прийняти ETH

receive() external payable {}

}

here is my last callback funtcion in contract
