Creat ERC721 Token:

function createToken(string memory _tokenURI) public returns (uint) {
    _tokenIds.increment();
    uint256 newItemId = _tokenIds.current();

    _mint(msg.sender, newItemId);
    _setTokenURI(newItemId, _tokenURI);
    setApprovalForAll(contractAddress, true);
    return newItemId;}

Put on Sale and transfer:

 function createSale( address nftContract,
uint256 itemId
) public payable nonReentrant {
uint price = idToMarketItem[itemId].price;
uint tokenId = idToMarketItem[itemId].tokenId;
require(msg.value == price, "Please submit the asking price in order to complete the purchase");
idToMarketItem[itemId].seller.transfer(msg.value);
IERC721(nftContract).transferFrom(owner, msg.sender, tokenId);
idToMarketItem[itemId].owner = payable(msg.sender);
idToMarketItem[itemId].sold = true;
_itemsSold.increment();
payable(owner).transfer(listingPrice); }

I was having same error and I came up with 2 solutions:

  1. In your hardhat.config.js, add manual gas limit in networks:

    your network: {
    url: `https://rinkeby.infura.io/v3/${process.env.PROJECT_ID}`,
    accounts: [privateKey],
    gas: 2100000,
    gasPrice: 8000000000,
}

  2. In your index.js file, instead of mainnet in Web3Modal, use your network:

    const web3Modal = new Web3Modal({
    network: "your network name",
    cacheProvider: true,
})
