Hi, I think your contract should be inherited from ReentrancyGuardUpgradeable, that is:

contract YOUR_CONTRACT is ReentrancyGuardUpgradeable {  <<<======= here!
    xxx;
    function mintWithFee(
        address _to,
        Fee[] memory _fees,
        AttributesStruct[] memory _attributes
    ) public nonReentrant payable {
        ...
    }
}
