Non-base58 character error in create Fungible token in Solana

'## 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)?'
