I'm more familiar with ethers, but trying to dig into this and looking into truffle https://www.trufflesuite.com/docs/truffle/getting-started/interacting-with-your-contracts
I'd guess that I could do something like this:
ethernaut.owner.estimateGas()
but that gets same error...
Shouldn't this be a gasless static call anyways...? What's going on here?
It looks from the same page like I should even be able to force it to be a gas-free call, like this:
ethernaut.owner.call()
same error...
I have zero clue why this is working, but I'm able to get an address back by running this:
await ethernaut.contract.methods.owner.call().call()
> '0x09902A56d04a9446601a0d451E07459dC5aF0820'
that's quite a mess, but I'll run with it for now.
fwiw:
this was me following the opening instructions in order, to play with the ethernaut contract a bit before moving on. It didn't work, had to use the workaround above, but it turned out to be relatively irrelevant--I'd just change the instructions to prevent someone else falling down this rabbit hole--as the rest of the course worked fine.
I appreciate you posting this because I ran into the same issue today.
I think specifying gas price like this is helping await ethernaut.owner({ gasPrice:0 })
This issue is acknowledged and already solved in this PR https://github.com/OpenZeppelin/ethernaut/pull/422 , once merged it should work normally
