Hi i recently, deployed a smart contract from remix ide to opensea, but encountred a problem.

Problem:
Images are not loading on opensea testnet.

opensea testnet:

contract code:

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

import '@openzeppelin/contracts/token/ERC1155/ERC1155.sol';
import '@openzeppelin/contracts/access/Ownable.sol';

contract AI is Ownable, ERC1155 {
// Base URI
string private baseURI;
string public name;

constructor()
    ERC1155(
        'ipfs://bafybeihnvw42eulx3cf6ibwnxk7eibycmwp5gdlr22juhtli6gm3uxucjy/{id}.json'
    )
{
    setName('GF');
}

function setURI(string memory _newuri) public onlyOwner {
    _setURI(_newuri);
}



function setName(string memory _name) public onlyOwner {
    name = _name;
}

function mintBatch(uint256[] memory ids, uint256[] memory amounts)
    public
    onlyOwner
{
    _mintBatch(msg.sender, ids, amounts, '');
}

function mint(uint256 id, uint256 amount) public onlyOwner {
    _mint(msg.sender, id, amount, '');
}

}

how can cahnge the code to get the image loading on opensea testnet.
