Lesson 5 Ether.js nonce error in deploy.js

[roychaadit]

I was writing the code for deploying the contract using ether.js and ganache as shown on github and in the tutorial. The following is my code:

  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying contract ...");
  const contract = await contractFactory.deploy();

  // const transactionReceipt = await contract.deploymentTransaction().wait(1);

  let currentFavoriteNumber = await contract.retrieve();
  console.log(`Current Favorite Number: ${currentFavoriteNumber}`);
  console.log("Updating favorite number...");
  let transactionResponse = await contract.store(7);
  let transactionReceipt = await transactionResponse.wait(1);
  currentFavoriteNumber = await contract.retrieve();
  console.log(`New Favorite Number: ${currentFavoriteNumber}`);

However, I am getting the following error which seems to be something pertaining to the nonce of the transaction.

Deploying contract ...
Current Favorite Number: 0
Updating favorite number...

Can someone help me fix this? Thanks

I do not get this error when I deploy the contract the first time. However, after the first time ganache always ends up throwing this error. Why is the nonce ordering not getting updated properly?

@roychaadit

Is this your whole code? Maybe something, which we do not see causing error..

@Neftyr @alfaqi
I just tried the code on ganache again. Did not change a thing. works perfectly now.
I do not know what caused the issue.
Thank you for the assistance.

As I said on start it had to be Ganache bug ;) glad it worked!

It might sometimes happen if it verifies the nonce itself before running against the vm

@roychaadit it's happening the same thing to me! The first time works, but then it doesnt. I'm glad that you got it working, but how long did it take? I hope it is a Ganache error!

Try to restart your system. It should work.
