This is my full deploy.js code:

  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  const wallet = new ethers.Wallet(

    provider
  );

  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf-8"
  );
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy({
    gasLimit: 1000000,
    gasPrice: 100000000000,
    to: null,
  });
  console.log(contract);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

First of all
you must not share your private key, from now and on don't use this account for real money.

make sure you're using this packages

{
  "dependencies": {
    "ethers": "^6.6.2",
    "solc": "^0.8.7-fixed"
  }
}

then run this command for compiling
npx solcjs --bin --abi --include-path node_modules/ --base-path . -o . SimpleStorage.sol

after that, you can deploy your contract.

fine the code working perfect,
the output is because of this console.log(contract);

@alfaqi :
i got the same issue with small difference at this lines:

...
code: -32000,
    name: 'RuntimeError',
    data: {
      hash: '0xc808a9e63502b13ee9b18c03bab1d42073b4f84cfe0b2e50d1f4053ddd14d69c',
      programCounter: 82,
      result: '0xc808a9e63502b13ee9b18c03bab1d42073b4f84cfe0b2e50d1f4053ddd14d69c',
      reason: null,
      message: 'invalid opcode'
    }
  },
  payload: {
    method: 'eth_sendRawTransaction',
...

Do you have an idea on how i can fix this ?

Thank you in advance

[alfaqi]

Hi @MehdiAbidri,
Try this

{
  "dependencies": {
    "ethers": "^6.6.2",
    "solc": "^0.8.19"  
  }
}

and make the version of solidity ^0.8.19

pragma solidity ^0.8.19;

[MehdiAbidri]

Hi @alfaqi ,

Thank you for the quick feedback.

I tried your suggestion, but i still have the same issue.

FYI, i had this before :

"dependencies": {
    "ethers": "^6.9.0",
    "fs": "^0.0.1-security",
    "fs-extra": "^11.2.0",
    "ganache-cli": "^6.12.2",
    "solc": "^0.8.23-fixed"
  },

don't hesitate to suggest other solution please, because i'am stuck right now.

here is more detail about the error that i'am getting :

[alfaqi]

did you modify the sol file?
then re-compile the sol file

[MehdiAbidri]

yes i did , i modified the sol file and the i re-compiled it.

the thing is , the transaction is working along with the error message.

but in the console, i'am blocked with this error message, i can't console anything

[alfaqi]

try delete all compiled files, restart ganache server and start over

[MehdiAbidri]

i deleted all comiled files (.abi and .bin) , restarted ganache and recompiled the sol file.
Unfortunately, i still have the error message.

again a transaction was done properly in ganache :

it seems to be something due to a recent update that's not takken into account in the course.

the code of lesson 5 works fine for you currently ?

Thank you agin for your support and quick feedbacks !

Mehdi

[alfaqi]

the code of lesson 5 works fine for you currently ?

Yes, actually I'm using hardhat, I think it's better than ganache.

[MehdiAbidri]

OK, i ll switch to lesson 6 then.
Thank you so much for your help
