Can't call read function on cloned UUPSUpgradeable contract

Support
1

I want to know why I can't call the getTokenId() read function on the cloned UUPSUpgradeable contract.
I cloned the contract and called the initialize() function on the instance correctly.
The write function createAgent() works fine, but the read function getTokenId() doesn't work, so I reverted it.
And I tested the entire original contract and it works fine.

:1234: Code to reproduce

contract BEP007Enhanced is
    IBEP007,
    ERC721Upgradeable,
    ERC721EnumerableUpgradeable,
    ERC721URIStorageUpgradeable,
    ReentrancyGuardUpgradeable,
    OwnableUpgradeable,
    UUPSUpgradeable
{
    using CountersUpgradeable for CountersUpgradeable.Counter;

    CountersUpgradeable.Counter private _tokenIdCounter;

    function initialize(
        address governanceAddress
    ) public virtual initializer {
        require(governanceAddress != address(0), "BEP007Enhanced: governance address is zero");

        __ERC721_init(name, symbol);
        __ERC721Enumerable_init();
        __ERC721URIStorage_init();
        __ReentrancyGuard_init();
        __Ownable_init();
        __UUPSUpgradeable_init();

        governance = governanceAddress;
        _transferOwnership(governanceAddress);
    }


    function createAgent(string memory metadataURI) external {
     _tokenIdCounter.increment();
        uint256 tokenId = _tokenIdCounter.current();

        _mint(to, tokenId);
        _setTokenURI(tokenId, metadataURI);
    }

    function getTokenId() external view returns (uint256) {
        return _tokenIdCounter.current();
    }
}

Ensure getTokenId() is a public or external view function and doesn’t have restrictions like onlyOwner or other modifiers that prevent access.
