Deploying ganache-local w/brownie: VM Exception while processing transaction: invalid opcode #6

GratefulDave · 2021-11-22T13:15:34Z

Thanks for an amazing class Patrick. I taught myself to code 3 years ago and wish I did it 33 years ago! :)

Issue

I am going through brownie simple storage part of this course. The initial deploy,.py works properly, but I keeping getting some variation of invalid opcode and the transaction is reverting when I try to deploy to ganache-local. I am able to run the tests in this project to development/ganache-cli, but fail with ganache-local and Rinkeby.

I am experiencing the same issues as I am with my own code base. I decided to test with a clone of this repo as 'bss' and replacing .env files with my info and am experiencing the same issues. I'm on MacOS.

I've also tried deleting build artifacts & redeploying ganache ui.

Environment

Brownie v.1.17.1
Ganache CLI v6.12.2 (ganache-core: 2.13.2)
Node v16.8.0
Npm v7.21.0
Truffle v5.0.22

The only part of the code that has been changed from the repo is adding the gas_limit. Still happy to share the code if request. For the life of me, I can't figure what invalid opcode is causing this to revert . . . Any help would be greatly appreciated!

Thanks in advance!

Thanks for the kind words!

This is likely due to the function you're calling... it doesn't like what you're doing. What happens when you use just the regular development network? Like brownie run scripts/deploy.py?

Or... did you install with pipx or pip?

Madgeniusblink · 2021-12-03T20:51:00Z

I am getting the same error after adding

`def withdraw():
fund_me = FundMe[-1]
account = get_account()
fund_me.withdraw({"from": account})

def main():
fund()
withdraw()`

GratefulDave · 2021-12-03T21:36:24Z

@PatrickAlphaC I installed with pipx. This was initially in the discussion here if you want to see all of the things we have tried. One user got it working. A few others have this same issue

PatrickAlphaC · 2021-12-06T19:47:38Z

There might be something wrong with your local network... what happens when you remove the network flag?

GratefulDave · 2021-12-06T20:19:22Z

If I import deploy_fund_me() and run it prior to running fund() & withdraw() to ganache-cli it works properly. If I don't do that it can't find an instance of FundMe[-1]. I believe that happens because ganache-cli isn't persistent.

PatrickAlphaC · 2021-12-06T21:16:27Z

Right, that makes sense. I'm thinking it's something wrong with your local chain... what happens when you try it on a testnet?

GratefulDave · 2021-12-06T21:23:29Z

If I run deploy.py and then fund_and_withdraw.py (w/o redeploying the mocks) I get the same error:

I also have ~17.5 ETH in my Rinkeby test account.

PatrickAlphaC · 2021-12-06T23:31:07Z

ValueError: Gas estimation failed: 'execution reverted: You need to spend more ETH!'

This means you're not sending enough ETH, and your entrance fee is off. How are you getting the entrance fee?

GratefulDave · 2021-12-07T01:11:21Z

I cloned your repo and added my .env file. Same code.

PatrickAlphaC · 2021-12-09T13:40:02Z

Do you have ETH in your metamask?

GratefulDave · 2021-12-09T19:27:32Z

I have Rinkeby eth as well. I was able to get this to work on ganache-local when I reinstalled on old machine. This appears to be a conflict with my installation/environment. @cromewar suggested I uninstall my versions of Python and try to reinstall them.

I was excited getting a new MacBook Pro M1 Max Pro next week, but I've heard that there are some issues with web3 and the new silicon. :/

I do appreciate your help @PatrickAlphaC. If you can suggest how I might be able to diagnose - that would be great. If not, please feel free to close this ticket.

PatrickAlphaC · 2021-12-13T16:21:08Z

Closing for now, if it's an issue with the M1... I won't be much help here sorry :/
