We can use convenience functions from the @xrplf/isomorphic package to convert string to hex or hex back to string: stringToHex, hexToString.

Also mentioned in xrpl.js reference:
https://js.xrpl.org/functions/convertStringToHex.html
https://js.xrpl.org/functions/convertHexToString.html

let hex = '';
for (let i = 0; i < credentialType.length; i++) {
const charCode = credentialType.charCodeAt(i);
const hexCharCode = charCode.toString(16).padStart(2, '0');
hex += hexCharCode;
}
credentialType = hex.toUpperCase();
}

// Prepare transaction
const transaction = {
"TransactionType": "CredentialCreate",
"Account": wallet.address,
"Subject": subject,
"CredentialType": credentialType
}

results = `\n\n===Preparing and Sending Transaction===\n\n${JSON.stringify(transaction, null, 2)}`
updateResults()

// Submit transaction
const tx = await client.submitAndWait(transaction, {autofill: true, wallet: wallet})

if (tx.result.meta.TransactionResult == "tesSUCCESS") {
// Parse for credential info
const parsedResponse = JSON.parse(JSON.stringify(tx.result.meta.AffectedNodes, null, 2))
const credentialInfo = parsedResponse.find( node => node.CreatedNode && node.CreatedNode.LedgerEntryType === "Credential" )
results = `\n\n===Create Credential Result===\n\n${JSON.stringify(credentialInfo.CreatedNode, null, 2)}`
} else {
results = `\n\n===Error===\n\n${JSON.stringify(tx.result.meta.TransactionResult, null, 2)}: Check codes at https://xrpl.org/docs/references/protocol/transactions/types/credentialcreate#error-cases`
}

updateResults()

} catch (error) {
results = `\n\n===Error===\n\n${error}`
updateResults()
}

client.disconnect()
