Check if you've made any typo mistake. I've also made similar mistakes in the past and most of them were because of typo mistake.

Look i solve that issue by downgrading my ethers version and did npm install and it worked . The node got deployed and it is showing the accounts and private key value and all and in the end it is showing this error .

now when i looked it up in StackOverflow it said to install this
"yarn add --dev hardhat @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers"
and i ran this command and when i am trying to do yarn hardhat node i am getting back the previous error
Now what should i do ?

@vamsikrishnapeketi As I said, it was working fine there were no issues.

This is my front end code .
When I am deploying the backend by yarn hardhat node it is not writing the abi and the contract address in the constants folder . Once check this please
