Contract revert reasons can mimic node errors

Ethers Version

insufficient funds, insufficient funds for intrinsic transaction cost, error message

Describe the Problem

Given a contract with a require like this one:

require(false, "Insufficient funds")

Ethers will (wrongly) say that the error was “Error: insufficient funds for intrinsic transaction cost”

I guess there’s some pattern matching going on with the returned error message.

This happens even with the hardhat network when a correct data is returned with the encoded error string.

Just ran into this. The code has been unchanged for years. The tests have gone through some tooling changes over the years, but are mostly unchanged. Started failing when we bumped to the latest version of hardhat.
