Non-base58 character error in create Fungible token in Solana

Question

I am trying to creat fungible token using metaplex(here)

The rest is working fine but when sending transaction there was error.

I found that createCreateMetadataAccountV2Instruction in add transaction has different type of props in guide. If I use typescript for this, it throws createMetadataAccountArgsV2 is not a type of PublicKey.

So I checked @metaplex-foundation/mpl-token-metadata and it's props were account: createMetadataAccountV2InstructionAccounts and programId?: PublicKey which is different from here.

How can I pass parameters in createCreateMetadataAccountV2Instruction?

Or if it's not a problem, what is wrong with the project(I just copy and paste the guide)?

Answer 1

Okay, Finally I create token.

I didn't use createCreateMetadataAccountV2Instruction. Instead I use createCreateMetadataAccountV3Instruction for transaction and it works fine.

const createNewTokenTransaction = new Transaction().add(
    SystemProgram.createAccount({
      fromPubkey: payer.publicKey,
      newAccountPubkey: mintKeypair.publicKey,
      space: MINT_SIZE,
      lamports: requiredBalance,
      programId: TOKEN_PROGRAM_ID,
    }),
    createInitializeMintInstruction(
      mintKeypair.publicKey,
      MINT_CONFIG.numDecimals,
      mintAuthority,
      freezeAuthority,
      TOKEN_PROGRAM_ID),
    createAssociatedTokenAccountInstruction(
      payer.publicKey,
      tokenATA,
      payer.publicKey,
      mintKeypair.publicKey,
    ),
    createMintToInstruction(
      mintKeypair.publicKey,
      tokenATA,
      mintAuthority,
      MINT_CONFIG.numberTokens * Math.pow(10, MINT_CONFIG.numDecimals),
    ),
    createCreateMetadataAccountV3Instruction(
      {
        metadata: metadataPDA,
        mint: mintKeypair.publicKey,
        mintAuthority: mintAuthority,
        payer: payer.publicKey,
        updateAuthority: mintAuthority,
      },
      {
        createMetadataAccountArgsV3:
        {
          data: ON_CHAIN_METADATA,
          isMutable: true,
          collectionDetails: null
        },
      }
    ),
  );

It's modified code.

Hope this will help you. :)
