Getting index out of range error when creating metaplex metadata account - token

Question

Why am I getting the following error when trying to create a metadata account using createCreateMetadataAccountV2Instruction from the #metaplex-foundation/mpl-token-metadata library?
SendTransactionError: failed to send transaction: Transaction simulation failed: Error processing Instruction 0: Program failed to complete

Here's my code:

PROGRAM_ID,
} from '#metaplex-foundation/mpl-token-metadata'
import {
Connection,
Keypair,
PublicKey,
sendAndConfirmTransaction,
Transaction,
} from '#solana/web3.js'
export const addMetadataToToken = async (
connection: Connection,
tokenMint: PublicKey,
tokenOwner: Keypair,
name: string,
symbol: string,
arweaveLink: string
) => {
const seed1 = Buffer.from('metadata', 'utf8')
const seed2 = PROGRAM_ID.toBuffer()
const seed3 = tokenMint.toBuffer()
const [metadataPDA, _bump] = PublicKey.findProgramAddressSync(
[seed1, seed2, seed3],
PROGRAM_ID
)
const accounts = {
metadata: metadataPDA,
mint: tokenMint,
mintAuthority: tokenOwner.publicKey,
payer: tokenOwner.publicKey,
updateAuthority: tokenOwner.publicKey,
}
const dataV2 = {
name,
symbol,
uri: arweaveLink,
// we don't need these
sellerFeeBasisPoints: 0,

}
const args = {
createMetadataAccountArgsV2: {
data: dataV2,

},
}
const ix = createCreateMetadataAccountV2Instruction(accounts, args)
const tx = new Transaction()
tx.add(ix)
const txid = await sendAndConfirmTransaction(connection, tx, [tokenOwner])
console.log(txid)
}

Answer 1

Turns out I was on trying to create metadata for a token on devnet, but was using a mainnet-beta rpc endpoint for the Connection class. Thus the token I was trying to create metadata for didn't exist.

This is a really Common Error Message that occurs when there is some issue with what you are passing to the program. So make sure everything that you are input to the program is correct. In 90% of the cases, it gets resolved when checking the inputs correctly.
