ProgramNotRecognizedError: The provided program name [mplCandyGuard] is not recognized in the [devnet] cluster

Hi..I am trying to mint NFTs from a candy machine v3 using the umi library as shown in this https://docs.metaplex.com/programs/candy-machine/minting . I am using the following code -
`import React from 'react'
import { Metaplex, walletAdapterIdentity } from "@metaplex-foundation/js";
import { useConnection, useWallet } from "@solana/wallet-adapter-react";
import { useMemo, useState } from "react";
import {
some,
generateSigner,
transactionBuilder,
} from "@metaplex-foundation/umi";
import { createUmi } from "@metaplex-foundation/umi-bundle-defaults";
import {mintV2} from "@metaplex-foundation/mpl-candy-machine";
import { setComputeUnitLimit } from "@metaplex-foundation/mpl-essentials";
import {
Connection,
} from "@solana/web3.js";

const MintNFT = () => {
const { publicKey, wallet } = useWallet();
const [nft, setNft] = useState(null);
const umi = useMemo(
() => createUmi(process.env.NEXT_PUBLIC_SOLANA_RPC_HOST),
[]
);
const connection = useMemo(
() => new Connection(process.env.NEXT_PUBLIC_SOLANA_RPC_HOST, "confirmed"),
[]
);
const candyMachineAddress = new PublicKey(
process.env.NEXT_PUBLIC_CANDY_MACHINE_ID
);
const metaplex = useMemo(
() => Metaplex.make(connection).use(walletAdapterIdentity(wallet)),
[connection, wallet]
);
let candyMachine;
let walletBalance;
const onClick = async () => {
// Here the actual mint happens. Depending on the guards that you are using you have to run some pre validation beforehand
// Read more: https://docs.metaplex.com/programs/candy-machine/minting#minting-with-pre-validation
// read candy machine state from chain
candyMachine = await metaplex
.candyMachines()
.findByAddress({ address: candyMachineAddress });
console.log(candyMachine);
await transactionBuilder()
.add(setComputeUnitLimit(umi, { units: 800_000 }))
.add(
mintV2(umi, {
candyMachine: candyMachine.address,
publicKey,
collectionMint: candyMachine.collectionMintAddress,
collectionUpdateAuthority: candyMachine.authorityAddress,
mintArgs: {
mintLimit: some({ id: 1 }),
solPayment: some({ destination: candyMachine.authorityAddress }),
},
})
)
.sendAndConfirm(umi);
};

return (

Here we mint the NFT

mint NFT

{nft && (

{nft.name}

)}

); }

export default MintNFT`

but on clicking the Mint NFT button I am getting the following error -
caught (in promise) ProgramNotRecognizedError: The provided program name [mplCandyGuard] is not recognized in the [devnet] cluster. Did you forget to register this program? If so, you may use "context.programs.add(myProgram)" to fix this.

Source: SDK
Can somebody please suggest what is wrong ?
I am using sugar-cli v2.1.1

This seems to the a Umi related issue, not Sugar. Did you try asking in Discord?

Closed for lack of activity, and appears to be related to Umi library, not Sugar.
