Hello, I receive an error when I try to get the PriceFeed Data while using the mainnet-fork network. Deployment works and interacting with it does work as wel, but when I try to get the price data it runs into the following error.
I don't have this problem when using the rinkeby network or when using other local networks. I also checked the network address in the config file and this is the correct address for retrieving the pricefeed on the mainnet. I added the line 'print(fund_me.getPrice())' in the deploy.py file to actually call the pricefeed, which makes it run into this error.
Does anyone have any idea why I run into this error? Thanks! |

Thanks for your response. Unfortunately this didn't work. I also tried infura instead of alchemy now. I figured out that the problem has something to do with ganache-cli. Retrieving contracts in brownie console is not possible via mainnet-fork, but it is possible with mainnet. |

In this case, maybe something is missing with your brownie config, did you add it correctly on that file the mainnet-fork? |

Your are most likely using a wrong configuration of mainnet-fork-dev,
please delete that network and add it again, also please double check the
price feed address to match the repo one.
Cheers

I fixed the problem. It turned out that I had to close Ganache completely and then run it. For some reason the local blockchain in ganache is being used when using mainnet-fork and leaving Ganache open, so for this reason it was impossible to read contracts from the mainnet. I still don't get this issue because ganache-cli automatically uses Ganache when it is running right? And I think Ganache is actually meant to be open all the time? @cromewar Do you have any idea why this is the case? Thanks for all the help! |
