Lesson 9 Error: TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

When I yarn hardhat deploy, I get the following error:

Error: ERROR processing skip func of C:\Users\daver\Documents\HardHat-freeCodeCamp\hardhat-smartcontract-lottery-fcc\deploy\00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

After searching and reading about this issue in the discussions, it is suggested that ethers@^6.0.0 has problems.
It is suggested to remove the package, delete the folder from node_modules and then, install a version of ethers@^5.0.0

Specifically,

1. I removed [email protected].
2. I deleted the 'ethers' folder from node_modules.
3. I installed [email protected] (yarn add --dev [email protected])
   (I did the above with different versions of ethers as well: ethers@5, [email protected])

After doing the above, I now get an error:

Error: ERROR processing C:\Users\daver\Documents\HardHat-freeCodeCamp\hardhat-smartcontract-lottery-fcc\deploy\00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'includes')

I went a step further and removed all dependencies and replaced them with the same versions as the instructor's repo. (as per comment: #4809 (reply in thread))

I still got the error:

Error: ERROR processing C:\Users\daver\Documents\HardHat-freeCodeCamp\hardhat-smartcontract-lottery-fcc\deploy\00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'includes')

I then tried to migrate to hardhat-toolbox. (as per comment #5426 (reply in thread))
When using the latest ethers (ether@^6.0.0) with the hardhat-toolbox dependencies, I get the error:

Error: ERROR processing skip func of C:\Users\daver\Documents\HardHat-freeCodeCamp\hardhat-smartcontract-lottery-fcc\deploy\00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'JsonRpcProvider')

...and, when using an older ethers (ethers@^5.0,0) with the hardhat-toolbox dependencies, I get this error

Error: ERROR processing C:\Users\daver\Documents\HardHat-freeCodeCamp\hardhat-smartcontract-lottery-fcc\deploy\00-deploy-mocks.js:
TypeError: Cannot read properties of undefined (reading 'includes')

The current state of my project is using the hardhat-toolbox dependencies with [email protected]
Here is my repo:

@CryptoNube Follow these steps;

1. Install the ethers version 5; npm install -D ethers@^5 --force
2. In the 00-deploy-mocks.js file fix typo here const { developmentChains } = require("../helper-hardhat-config")
3. In the same file, fix typo here await deploy("VRFCoordinatorV2Mock",
4. Now you will face error getContract is not a function so override hardhat ether with hardhat deploy ethers using this command npm install --save-dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers --force

Make sure to use the --force flag whenever you see errors in command for conflicts.

Ahhh...it's the developmentChains typo! Darn!
Thank you very much for finding that and, thanks for the reminder to use hardhat-deploy-ethers for hardhat ethers, now that I have merged to the hardhat-toolbox. I would have got stuck on that.

Is there some way we can do it using ethers6 ? like without having to down grade to 5

@alymurtazamemon I did step 1 and 4 in your answer. Mock got deployed but am getting an error TypeError: (0 , ethers_1.getAddress) while deploying Raffle contract.
