E brownie.exceptions.VirtualMachineError: revert about chainlink-mix HOT 3 CLOSED

hi @upalchowdhury thanks for raising this. Looks like you're having an issue with a contract and script that you created as opposed to one of the ones that comes in the chainlink-mix project? Can you confirm if you get the same output if you use the PriceFeedConsumer contract and the 02_read_price_feed.py script?

If the contract and script I mentioned above works ok, and it's just your custom script and contract that has issue, can you please raise this as a post on StackOverflow, and we can action there, as it's unrelated to this chainlink-mix project https://stackoverflow.com/tags/chainlink

from chainlink-mix.

@pappas999 Thanks for your response !!

I got it working. thanks for your hint on scripts which made me reinstall ganache cli. My initial port was 7545, changed it to 8545 might have solved the issue but not 100% sure.

I used solc 0.6.6 plus chainlink 0.6 contracts for this test.

One observation on the "02_read_price_feed.py script" the PriceFeedConsumer[-1] was throwing error but since i changed it read it from brownie-config.yaml it works.

====================

test/pricefeedtest.py works fine except it does not return or print anything, which might be expected. anyhow thanks again for your quick response.
