network.config is not a function #4688

I know I should be able to troubleshoot this on my own, but I've been on it around 30 minutes already and can't find where the problem is ocurring. Error promptError: ERROR processing /home/philipo0/hh-fcc/hardhat-fund-me-fcc/deploy/01-deploy-fund-me.js: helper-hardhat-config.jsconst networkConfig = {

Thanks for the reply, it fixed that problem, though I ran into 2 other rather simpler problems i'll write them in a separate discussion. |

Hi @philipo0 , You used parentheses instead of brackets in this line : Pay extra attention to the error message. It tells you the line where the error is (in this case 31/34) and gives you information. Here, you're told "networkConfig is not a function" which means that you wrote networkConfig() somewhere. Cheers 😄 |

Hi @philipo0 ,
You used parentheses instead of brackets in this line :
ethUsdPriceFeedAddress = network.config(network.name)["ethUsdPriceFeed"]It should instead be
ethUsdPriceFeedAddress = network.config[network.name]["ethUsdPriceFeed"]Pay extra attention to the error message. It tells you the line where the error is (in this case 31/34) and gives you information. Here, you're told "networkConfig is not a function" which means that you wrote networkConfig() somewhere.
Cheers 😄
