In your hardhat.config you didn't specify the solidity version. specify whatever solidty version you are using inside module.exports at the first position as stated below.

module.exports = {
solidity: 0.8.17 ,
defaultNetwork: "hardhat",
}

@Cointerior I am too facing same issue have you got any solution

[N-dcool]

@Cointerior I solved this issue , I posted how to solve this issue on Ethereum Stackoverflow, here https://ethereum.stackexchange.com/questions/146902/before-each-hook-for-sets-the-aggregator-addresses-correctly-typeerror-cann/146903#146903
inform me if it solved your problem! Thanks you

[N-dcool]

Mark this issue as answered please @N-dcool Thank you : )

@Cointerior is supposed to mark this issue answered!

[Cointerior]

@N-dcool I've tried your solution on ethereum stackoverflow and i got a different error this time

An unexpected error occurred:

Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\IJAOLA OMONIYI\Desktop\my-sol\p1\node_modules\@ethersproject\abi\lib\index.js from C:\Users\IJAOLA OMONIYI\Desktop\my-sol\p1\node_modules\hardhat-deploy\dist\src\utils.js not supported.
Instead change the require of index.js in C:\Users\IJAOLA OMONIYI\Desktop\my-sol\p1\node_modules\hardhat-deploy\dist\src\utils.js to a dynamic import() which is available in all CommonJS modules.

Try calling your fundMe.priceFeed like this an object instead of as a function const response = await fundMe.priceFeed; remove "()" brackets

[nstapleton1]

This fix worked for me - thank you. There have been other examples during the course where the latest ethers package has proven unstable.

[sodexx7]

Thanks your sharing, which solved my current problem.

[alymurtazamemon]

@Cointerior Leave your repo link, if you are still facing the issue.

[alymurtazamemon]

@Cointerior Your project had issues with hardhat ethers which come from hardhat deploy (some version conflicting issues). I have pushed the fixed code on your repository now it is working fine.

[Atharv-02]

what changes did you do @alymurtazamemon as even I am facing the same issue

[Cointerior]

@alymurtazamemon Thanks bro, I've merged it

[alymurtazamemon]

@Atharv-02 Just use compatible dependencies for his repo, if you are facing an issue then create a discussion and leave your repo with the issue you are facing.

@Cointerior If it is resolved then mark the answer to close the discussion.

[eashan-d]

Can you please share the compatible dependencies, the repo is unavailable

[satishnvrn]

FYI: I solved the same issue with the latest version of ethers and hardhat-toolbox. My solution is in this repo. @Cointerior @alymurtazamemon

[cah311]

can you please take a look at my repo? https://github.com/cah311/hardhat-fund-me-fcc. I have tried every different solution on here and I still cant get past the first test. I tried taking different parts from your code as well.

[satishnvrn]

@cah311 I'll definitely try with your code. Can you tell me the node version you are using just to make sure everything is the same in both our environments?

[satishnvrn]

I fixed your code. Please check this PR: cah311/hardhat-fund-me-fcc#1 and feel free to merge it.
Ask me any questions in the PR about the changes I made.
For further changes check the main branch of my repo: https://github.com/satishnvrn/hardhat-fund-me-sat/tree/main

[stevengregori92]

I changed
deployer = (await getNamedAccounts()).deployer
to
deployer = await getNamedAccounts()

Suddently it worked. is it fine?
