How to fix overflow error when testing with Hardhat

Question

I'm getting an BigNumber overflow error when running hardhat tests. How do I fix this?

const ownerBalance = await MyToken.mint(
   owner.address,
   "ipfs://".length,
   { value: ethers.BigNumber.from(50000000000000000) }
);

If you are getting the error from the BigNumber part, then I suggest you construct the number like this: ethers.utils.parseUnits("5", 16).
