Contract revert reasons can mimic node errors

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.

Thanks! I’ll look into this asap.

This has been fixed in 5.6.6. Try it out and let me know if you still have any issues.

Thanks! :)

I think this is working correctly when the gas is estimated, but the same problem shows up if you set a specific gas limit in the overrides 😢

I thought I tried that too? I’ll test it out again shortly.

I just tried out all combinations of "view" vs. "send" and "with" vs "without" a gasLimit, and all returned the appropriate error (CALL_EXCEPTION or UNPREDICTABLE_GAS_LIMIT, depending); none returned the mimicked INSUFFICIENT_FUNDS error.

Can you provide an example?
