我正在使用 ERC1155 的智能合约（Open Zeppelin），它在 Remix 中正确编译，但是当我在 Visual Code 中编译时，我收到

ParserError：预期的标识符，得到'LParen'

智能合约可以成功部署到 Rinkeby 测试网。但是，当我尝试在 Etherscan 中验证合约时，它会给我以下消息：

Note: Unable to determine contructor arguments, please check and replace with correct values (6e65746f70656e2e707974686f6e616e7977686572652e636f6d2f7374617469632f6d6574616461646f732f6d6574616461646f7370617261657263313135352e747874)

这是构造函数的代码。

    address public creator; // Used as the URI for all token types by relying on ID substitution, e.g. https://token-cdn-domain/{id}.json
    event CreateToken(address creator, address owner, uint256 _id, uint256 _value,string uri, uint256 _urihash);

    constructor ()  ERC1155("netopen.pythonanywhere.com/static/metadados/metadadosparaerc1155.txt") {
        creator=msg.sender;
    }

我怎样才能解决这个问题？
