Uncaught Error: invalid hexlify value (operation="checkSafeInteger", fault="out-of-safe-range", value=1000000000000000000, code=NUMERIC_FAULT, version=bytes/5.5.0)

I use this version:
https://cdn.ethers.io/lib/ethers-5.5.4.esm.min.js

My code:

<script type="module">
import { ethers } from "./ethers-5.5.4.esm.min.js";
console.log(ethers.utils.hexlify(1000000000000000000));
</script>

I get this error:

ethers-5.5.4.esm.min.js:1 Uncaught Error: invalid hexlify value (operation="checkSafeInteger", fault="out-of-safe-range", value=1000000000000000000, code=NUMERIC_FAULT, version=bytes/5.5.0)

Please read the note on IEEE 754 for more info on using numbers in JavaScript.

For your purposes, you would probably want to use BigNumber.from("1000000000000000000").toHexString(). Notice it is a string, which is safe for large values in JavaScript.

Thanks, It's works: console.log(ethers.BigNumber.from("1000000000000000000").toHexString());
