Lesson 7: FundMe.test.js ABICoder is not a constructor

[cah311]

Here is the error I am getting:

 FundMe
    constructor
      ✔ sets the aggregator addresses correctly
    fund
      1) Fails if you dont send enough ETH


  1 passing (3s)
  1 failing

  1) FundMe
       fund
         Fails if you dont send enough ETH:
     TypeError: AbiCoder is not a constructor

There is not alot on this error as it seems fairly new. I only seen one solution and that was to delete hardhat-ethers, upgrade ethers to 6, and run deploy scripts manually.

Would this not make the deploy scripts we write for this lesson redundant? Is there a better solution that I am just missing?

Could you upload your repo here

Maybe you have the same problem with this question
Check out it: #5683

Here is my repo: https://github.com/cah311/hardhat-fund-me-fcc

I actually commented on that problem. The answer given isnt super clear. What I was wondering on that is, if we switch to hardhat 6 , what does it exactly mean to leave hardhat-deploy and use the hardhat way to deploy and test our contracts?

[cah311]

If I follow the reccomendation given in problem #5683, I get this error:

  FundMe
    constructor
      1) "before each" hook for "sets the aggregator addresses correctly"


  0 passing (14ms)
  1 failing

  1) FundMe
       "before each" hook for "sets the aggregator addresses correctly":
     ReferenceError: getNamedAccounts is not defined
      at Context.<anonymous> (test/unit/FundMe.test.js:11:9)
      at processImmediate (node:internal/timers:471:21)

This is another open problem on here. Ive found different solutions that just generally lead me back to this problem

Hi @cah311! I would suggest you to add some package in your hardhat.config.js file at the top. And then try to run the test again. I am sure it will run. As I faced the same issue and after resolving the same way my issue get fixed!

Here is the package to be added on the file:

require("@nomicfoundation/hardhat-verify");
require('@nomicfoundation/hardhat-ethers');
require('hardhat-deploy-ethers');

I hope this will work for you as well 👍🏻

Hey thanks for your tip. Unfortunatly it didnt work. It gave me this error instead:

hardhat-fund-me-fcc carson$ yarn hardhat test
Error HH210: Redefinition of task verify failed. Unsupported operation adding positional param definitions in an overridden task.

For more info go to https://hardhat.org/HH210 or run Hardhat with --show-stack-traces

Hey thanks but this didtn work. It ended up creating way more dependency errors and essentially just sent me in a circle of installing and unistalling different plug-ins
