Hello @Siaeua

Please show me your package.json -> you can also make sure you are using exact same packages as course repo.

Hi @Siaeua

So the issue is coming from ethers version as you are using ethers v6, which has different syntax than ethers v5. Whole course is built on ethers v5, so please either downgrade your ethers as below to stick to v5 or edit your code to match ethers v6 -> check their documentation but for getting address for example instead of .address property you should be using getAddress() function.

To downgrade your ethers to match course:

1. Delete yarn.lock and node_modules
2. Copy package.json from course -> ensure it has "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13" in it.
3. Install your new packages with running yarn command.

it worked!!! thank you so much.
