Can't create child contract in mainnet?

Question

address[] child;

function createChildContract() onlyOwner public{
    address newChild = new Child(msg.sender);
    child.push(newChild);
    emit ChildCreated(newChild);
}

contract Child {
   address public owner;

constructor(address _owner) public{
    owner = _owner;
}

function getOwner() external view returns(address){
    return owner;
}

I can make child contracts with this code in testnet but in mainnet it dosen't work.

Does mainnet just impossible to create child contract? or my code is wrong?

Answer 1

Your transactions to the contract show that you aren't including any tx data, meaning you aren't calling createChildContract.
