This error means that an object you are trying to convert to hex (toHexString()) is undefined. Check that the variable is initialized before calling .toHexString(): const value = ethers.BigNumber.from("1000");
console.log(value.toHexString()); // WorksIf this happens with a transaction or a return value, ensure it is correctly assigned. |
