formatBytes32String not working in ethers v6

Question

const ethers =  require('ethers');

async function createBytes (args) {
   const name = args[0];
   const bytes = ethers.utils.formatBytes32String(name);
   console.log('name: ',bytes)
}

createBytes(process.argv.slice(2));

What's wrong in it and i can't understand this error. I am trying to run js file through a powershell

You are using the old v5 syntax.

formatBytes32String has been renamed to encodeBytes32String in v6:

// v5:
bytes32 = ethers.utils.formatBytes32String(text)
text = ethers.utils.parseBytes32String(bytes32)

// v6:
bytes32 = ethers.encodeBytes32String(text)
text = ethers.decodeBytes32String(bytes32)

Change your code to the following:

const ethers =  require('ethers');

 async function createBytes (args) {
    const name = args[0];
    const bytes = ethers.encodeBytes32String(name);
    console.log('name: ',bytes)
}

createBytes(process.argv.slice(2));
