Transaction loads a writable account that cannot be written

[ileFixDev]

Good day, I am currently writing a small program that mints an NFT using the Candy Machine ID. For this, I have https://github.com/metaplex-foundation/metaplex/blob/master/js/packages/cli/src/candy-machine-v2-cli.ts mint_one_token recoded in Go using your libraries. However, I always get as error:

Transaction simulation failed: Transaction loads a writable account that cannot be written.

Do you have any idea what this could be? Thank you very much!

Here is my code:

Hi @ileFixDev

That's a lot of surface for a potential bug to hide into.

Try this: disable the preflight check so that the transaction will execute and fail leaving behind a log.

That way it's going to be a lot easier to understand what's the issue and where.

    sig, err := sendAndConfirmTransaction.SendAndConfirmTransactionWithOpts(
        context.TODO(),
        connection,
        wsClient,
        tx,
        true, // skip preflight and let the tx execute so you have a log to look at and try to understand where it fails.
        rpc.CommitmentFinalized,
    )
       fmt.Println(sig, err)

[ileFixDev]

Hey, thanks for your answer, I have tried a little bit yesterday and got a little further. You can find the new code below. Although it should now be exactly the same as in the TS code, I get with as well as without preflight:

(*jsonrpc.RPCError)(0xc0001c0720)({

  }
 }
})

The Publickey: A7BK7wAtG36S3ZHnxRfM4dzHeh5oS7RvzFA9aDNSmw6 points to the mint.PublicKey() However, I have no idea why that is not accepted, in the TS version it is used the same way.

[gagliardetto]

Maybe the mint must be owned by the candy machine?

    instructions = append(instructions,
        system.NewCreateAccountInstructionBuilder().
            SetOwner(userKeyPair.PublicKey()). // the owner should be the candymachine, cndy3Z4yapfJBmL3ShUp5exZKqR3z33thTzeNMm2gRZ
            SetNewAccount(mint.PublicKey()).
            SetSpace(82).
            SetLamports(min).
            SetFundingAccount(userKeyPair.PublicKey()).
            Build(),

[ileFixDev]

If I set the SetOwner() to cndy3Z4yapfJBmL3ShUp5exZKqR3z33thTzeNMm2gRZ I get the same error. But for fun, I put the TOKEN_PROGRAM_ID (TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA) from the TS code and now I get the following error:

[gagliardetto]

I think that means that the associated token account does not exist (you need to create it).

[gagliardetto]

[gagliardetto]

Wait, nope, sorry.

[ileFixDev]

Okay all fine xD

[gagliardetto]

found it

you're calling

    userTokenAccountAddress, err := getTokenWallet(mint.PublicKey(), userKeyPair.PublicKey())

but getTokenWallet is func getTokenWallet(wallet solana.PublicKey, mint solana.PublicKey) (solana.PublicKey, error) {

(wrong param order)

[ileFixDev]

Yes, you are right!

Now I ended up with custom program error: 0x7d1 Is there an error code list somewhere?

[gagliardetto]

Okay

To find out what that error means, this is the flow:

• Convert hex 0x7d1 to decimal = 2001
• Check on https://anchor.so/errors what range the error belongs to. In this case 2001 is ConstraintHasOne, noted as has_one. (you could also check here: https://github.com/project-serum/anchor/blob/2390a4f16791b40c63efe621ffbd558e354d5303/lang/src/error.rs#L47)
• Find what the constraint means; in this case: https://book.anchor-lang.com/chapter_3/the_accounts_struct.html?highlight=has_one#constraints
• Find the full constraint notation in the candy machine source code: https://github.com/metaplex-foundation/metaplex-program-library/blob/f0ba11e0b490e346cfa581a236602d4ed1d0fa6a/candy-machine/program/src/lib.rs#L705-L707

I don't fully understand it. I supposedly means that the wallet must be the owner of the candy_machine, but that doesn't make sense to me.

[gagliardetto]

Update:

Reading here: https://docs.rs/anchor-lang/latest/anchor_lang/derive.Accounts.html

The constraint means that the data on the candy machine account is a CandyMachine struct, and the field Wallet of that struct must be equal to wallet pubkey.

[gagliardetto]

Here:

    instructions = append(instructions,
        nftcandymachinev2.NewMintNftInstructionBuilder().
            SetCreatorBump(creatorBump).
            SetCandyMachineAccount(candyMachineAddress).
            SetCandyMachineCreatorAccount(candyMachineCreator).
            SetPayerAccount(userKeyPair.PublicKey()).
            SetWalletAccount(userKeyPair.PublicKey()).

The SetWalletAccount(. refers to the wallet of the candy machine, not the user minting.

[gagliardetto]

See here:

https://github.com/metaplex-foundation/metaplex-program-library/blob/f0ba11e0b490e346cfa581a236602d4ed1d0fa6a/candy-machine/program/src/lib.rs#L49-L50

[gagliardetto]

You need to fetch the candy machine, parse it, and use the Wallet field.

    candyMachine, err := anchorProram.GetAccountInfo(context.TODO(), candyMachineAddress)
    if err != nil {
        return "", err
    }
    dec:=bin.NewBorshDecoder(candyMachine.Value.Data.GetBinary())
    var cm CandyMachine
    err= dec.Decode(&cm)
    if err != nil {
        return "", err
    }
    // use cm.Wallet in SetWalletAccount(cm.Wallet)
    fmt.Println(cm.Wallet)

[ileFixDev]

Ohhh yes. That worked. Many, many thanks for your dedicated help. <3

[gagliardetto]

Ohhh yes. That worked. Many, many thanks for your dedicated help. <3

Awesome! :smile:

Closing.

[AlienRecall]

@gagliardetto Hi, I don't want to bother with another issue, so I'll ask here as it's almost the same problem. I'm trying to mint on this candy machine 9TXUXT8WT5HbTDXXin16iFdtgsvR2KnifCZuor41JSVQ but when I send the transaction I get:

I see that there can be problems with my mintTo instruction, so this is how I create it:

mintTo := token.NewMintToInstructionBuilder().
        SetAmount(1).
        SetMintAccount(mint.PublicKey()).
        SetDestinationAccount(userTokenAccountAddress).
        SetAuthorityAccount(payer.PublicKey())

I have tried several things but none worked, can you help me on this? Obv I have tried, with typescript and it worked, so I'm sure that I'm doing something wrong, what it could be?

[gagliardetto]

Hi @AlienRecall

What group of instructions does return that error?

[gagliardetto]

AFAIK you must mint through the candy machine program (it has a mint instruction)

[AlienRecall]

Sorry for the miss understanding, I'm trying to mint a NFT

[gagliardetto]

You're trying to mint an NFT from a candy machine, right?

[AlienRecall]

Yes, I'm trying to write a script that mints a NFT with a given CandyMachineID, same as the guy in this issue

[gagliardetto]

Added an example: https://github.com/gagliardetto/metaplex-go/blob/main/examples/mint-from-candy-machine-v2/mint.go

Let me know if that doesn't work.

[AlienRecall]

Thanks for your time on this example, that helped me a lot, but initially it wasn't working because you missed SetFundingAccount(userKeyPair.PublicKey()). in the NewCreateAccountInstructionBuilder function, after that I was getting Transaction simulation failed: Error processing Instruction 0: custom program error: 0x3, then I've tried to change the SetSpace value always on the instruction 0, from candyMachineRaw.Value.Lamports to uint64(82), after that I got Transaction simulation failed: Error processing Instruction 4: custom program error: 0xa7, what could be the problem? I have to say that I've just copy/pasted your code and changed from MainNetBeta to DevNet, and obviously I've set my secret key and a candy machine

[gagliardetto]

I put the wrong candymachinev2 program ID; fixed, see: https://github.com/gagliardetto/metaplex-go/blob/main/examples/mint-from-candy-machine-v2/mint.go

[AlienRecall]

the error still persist, I get Transaction simulation failed: Error processing Instruction 4: custom program error: 0xa7 and Transaction simulation failed: Error processing Instruction 0: custom program error: 0x3 if I use candyMachineRaw.Value.Lamports as SetSpace value

[gagliardetto]

Updated. Try now.

[AlienRecall]

I had to add SetFundingAccount(userKeyPair.PublicKey()). at instruction 0 (NewCreateAccountInstructionBuilder) or it would gave me insufficient account keys for instruction, after that I get Transaction simulation failed: Error processing Instruction 1: invalid account data for instruction

[gagliardetto]

Try now

[AlienRecall]

the error now is
