I'm trying to deploy a trivial faucet program which compiles OK with remix but I get the following error. "Gas requirement of function Faucet.withdraw(uint256) high: infinite. " This means that while it compiles I cannot deploy it to my Ganache blockchain. I understand the concept of gas for a function but I cannot see what is potentially infinite here: I have put a tiny limit on any withdrawal amount.

Could someone please explain?

pragma solidity >=0.5.0; contract Faucet { function withdraw(uint256 withdraw_amount) public { require(withdraw_amount <= 2000000); msg.sender.transfer(withdraw_amount); } // Accept any incoming amount function () external payable {} }
