Incorrect return values for ERC20 functions results in failure when interacting with other contract , as the return value is missing.
Proof of Concept
ApproveLike (contracts/L1/gateway/L1Migrator.sol#67-69) has incorrect ERC20 function interface:ApproveLike.approve(address,uint256) (contracts/L1/gateway/L1Migrator.sol#68)
