When I try to deploy this smart contract address Using Remix IDE with Injected Provider Metamask wallet (Polygon Mumbai testnet)
//SPDX-License-Identifier: Unlicensed
pragma solidity ^0.8.4;
import "./ERC721.sol";
contract ComicBookCollection {
ERC721Template public nftTemp;
struct Data {
address owner;
string uri;
string name;
string symbol;
uint256 totalSupply;
uint256 mintPrice;
}
struct CollectionsbyOwner {
address[] nftcollections;
}
// owner to collection to collectiondata
mapping(address => mapping(address => Data)) public CollectionRecords;
// owner address to collection
mapping(address => CollectionsbyOwner) CollectionOwner;
modifier isOwner(address _nftCollection) {
Data memory data = CollectionRecords[msg.sender][_nftCollection];
require(data.owner == msg.sender, "You are not the owner");
_;
}
function createCollection(
string memory _name,
string memory _uri,
uint256 _totalSupply,
uint256 _mintPrice,
uint256 _startDate,
uint256 _expirationDate
) public {
nftTemp = new ERC721Template(_name, _uri, _totalSupply, _mintPrice, _startDate, _expirationDate);
CollectionsbyOwner storage tempCollections = CollectionOwner[msg.sender];
tempCollections.nftcollections.push(address(nftTemp));
transferOwner(msg.sender, address(nftTemp));
}
function getCollections(address _owner) public view returns(CollectionsbyOwner memory){
return CollectionOwner[_owner];
}
function updatePrice(uint256 _newPrice, address _nftCollection)
public
isOwner(_nftCollection)
{
CollectionRecords[msg.sender][_nftCollection].mintPrice = _newPrice;
}
function updateUri(string memory _newUri, address _nftCollection)
public

}
function transferOwner(address newOwner, address _nftCollection)
internal
{

}
I got this error
