How to create a validator using @cosmjs/stargate library?

[anshulWeb3]

I am trying to create a validator using cosmjs/stargate library. But I am stuck at an error:
{ code: 2, codespace: 'sdk', log: 'unable to resolve type URL /tendermint.PubKeyEd25519: tx parse error' }

Please take a look at the code below and help me find out the appropriate path to create a validator through client library using Node.js.

//==========================================================================================
import { DirectSecp256k1HdWallet,Registry } from "@cosmjs/proto-signing"; import { SigningStargateClient , defaultRegistryTypes,GasPrice} from "@cosmjs/stargate"; import {MsgCreateValidator} from "cosmjs-types/cosmos/staking/v1beta1/tx" import {PublicKey} from "cosmjs-types/tendermint/crypto/keys"

async function createValidator() {
// Replace the following values with your actual data
const mnemonic = "forward melody elevator label awkward uniform deposit day pen office explain crack ghost armor elite drop ramp direct girl blush much brisk chief train";
const chainId = "sim_904-3";
const validatorMoniker = "MyValidator";
const validatorIdentity = "Identity information";
const validatorWebsite = "https://myvalidator.com/";
const validatorSecurityContact = "[email protected]";
const validatorDetails = "Details about my validator";
const commissionRate = "0.1";
const commissionMaxRate = "0.2";
const commissionMaxChangeRate = "0.01";
const delegationAmount = "1000000";

const coin = {
denom: "stake",
amount: "200000000000",
}; // The amount of tokens you want to delegate to your own validator (you can adjust this)

const registry = new Registry();
const wallet = await DirectSecp256k1HdWallet.fromMnemonic(mnemonic, {
prefix: "cosmos",
});
const [{ address: senderAddress }] = await wallet.getAccounts();

const myRegistry = new Registry(defaultRegistryTypes);
myRegistry.register("/cosmos.staking.v1beta1.MsgCreateValidator", MsgCreateValidator);
myRegistry.register("/tendermint.crypto.PublicKey", PublicKey);
const gasPrice = GasPrice.fromString("0.0000001stake");
const client = await SigningStargateClient.connectWithSigner(
"http://localhost:26657/",
wallet,
{
gasPrice: gasPrice,
registry: myRegistry,
}
);

// Sign and broadcast the transaction
const fee = {
amount: [{ denom: "stake", amount: "500" }],
gas: "200000",
};

const sendMsg = {
typeUrl: "/cosmos.staking.v1beta1.MsgCreateValidator",
value: MsgCreateValidator.fromPartial({
description: {
moniker: validatorMoniker,
identity: validatorIdentity,
website: validatorWebsite,
securityContact: validatorSecurityContact,

},
commission: {

maxChangeRate: commissionMaxChangeRate,
},
minSelfDelegation: delegationAmount,

value: Uint8Array.from(Buffer.from("KboqFFQffL+9c5Wj45hoySwlYd5OtmbREZ7kEUPuIgs=", "base64")), // The public key will be filled automatically by the library
},
value: coin,
}),
};
const txResult = await client.signAndBroadcast(senderAddress, [sendMsg], fee,"Create Validator");
return txResult;
}

createValidator()
.then((txResult) => {
console.log("Validator creation transaction result:", txResult);
})
.catch((error) => console.error("Error creating validator:", error));
