UpdateMetadataAccount not working

I did not find an example of how exactly to use UpdateMetadataAccount correctly and tried it out.

In MetadataProgramData.cs Line 171

Solnet.Metaplex/Solnet.Metaplex/MetadataProgramData.cs

Line 171 in 1e64536

    
           writer.Write( (byte) MetadataProgramInstructions.Values.CreateMetadataAccount );

should maybe be

writer.Write( (byte) MetadataProgramInstructions.Values.UpdateMetadataAccount );

instead of

writer.Write( (byte) MetadataProgramInstructions.Values.CreateMetadataAccount );

?
I tried it out using

var tx = MetadataProgram.UpdateMetadataAccount(mintMetadataPublicKey, updateAuthority, updateAuthority, new MetadataParameters()
            {
                creators = new List<Solnet.Metaplex.Creator>()
                  {
                       new Solnet.Metaplex.Creator(updateAuthority, 100)
                  },
                name = "customname",
                sellerFeeBasisPoints = 200,
                symbol = "",
                uri = "customurl"
               
            }, false);
            
            
var blockHash = _client.GetRecentBlockHash();
byte[] TX1 = new TransactionBuilder()
                .SetRecentBlockHash(blockHash.Result.Value.Blockhash)
                .SetFeePayer(wallet.Account)
                .AddInstruction(tx)
                .Build(new List<Account> { wallet.Account });
                
                var txSim = _client.SimulateTransaction(TX1);

and I get following error:

{"jsonrpc":"2.0","result":{"context":{"slot":99070261},"value":{"accounts":null,"err":{"InstructionError":[0,"InvalidError"]},"logs":["Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s invoke [1]","Program log: Error: BorshIoError","Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s consumed 3732 of 200000 compute units","Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s failed: program returned invalid error code"]}},"id":3}

What I'm doint wrong and could you please share an working example?

Encode payload data for CreateMetadataAccountV3 (with Collections Details)

I am aware that there has not yet been released a version which takes into account certified collections. Anyway, I do plan to make the necessary adjustments to the existing code so as to allow creating a collection.

From my understanding, for creating a certified collection, the following are needed:

Changing MetadataProgram.CreateMetadataAccount function so as to also encode the collectionDetails. However, I tried to change it according to the order, offsets and sizes of arguments listed here https://docs.metaplex.com/programs/token-metadata/instructions#create-a-metadata-account and I don't seem to manage to get it working. My modified version of MetadataProgram.CreateMetadataAccount is:

private static byte[] EncodeCreateMetadataAccountData(MetadataParameters parameters, int? collectionDetailsSize = null, bool isMutable = true)
        {
            byte[] bytes = Encoding.UTF8.GetBytes(parameters.name);
            byte[] bytes2 = Encoding.UTF8.GetBytes(parameters.symbol);
            byte[] bytes3 = Encoding.UTF8.GetBytes(parameters.uri);
            MemoryStream memoryStream = new MemoryStream();
            BinaryWriter binaryWriter = new BinaryWriter(memoryStream);
            binaryWriter.Write((byte)0);
            binaryWriter.Write(bytes.Length);
            binaryWriter.Write(bytes);
            binaryWriter.Write(bytes2.Length);
            binaryWriter.Write(bytes2);
            binaryWriter.Write(bytes3.Length);
            binaryWriter.Write(bytes3);
            binaryWriter.Write((ushort)parameters.sellerFeeBasisPoints);
            int num;
            if (parameters.creators != null)
            {
                List<Creator> creators = parameters.creators;
                num = ((creators != null && creators.Count < 1) ? 1 : 0);
            }
            else
            {
                num = 1;
            }

            if (num != 0)
            {
                binaryWriter.Write((byte)0);
            }
            else
            {
                binaryWriter.Write((byte)1);
                binaryWriter.Write(parameters.creators.Count);
                foreach (Creator creator in parameters.creators)
                {
                    byte[] buffer = creator.Encode();
                    binaryWriter.Write(buffer);
                }
            }

            // collection - ADDED BY ME
            binaryWriter.Write((byte)0);

            // uses  - ADDED BY ME
            binaryWriter.Write((byte)0);

            binaryWriter.Write(isMutable);

            // - whole below if-else block ADDED BY ME
            if (collectionDetailsSize != null)
            {
                binaryWriter.Write((byte)1);

                byte[] collectionDetailsByteArray = new byte[8];
                var collectionDetailsSizeBytes = BitConverter.GetBytes(collectionDetailsSize.Value);

                collectionDetailsSizeBytes.CopyTo(collectionDetailsByteArray, 0);

                binaryWriter.Write(collectionDetailsByteArray);
            }
            else
            {
                binaryWriter.Write((byte)0);
            }

            return memoryStream.ToArray();
        }

I always get a deserialization exception from the on-chain program. I am using testnet at the moment. Can you help me get the encoding of the collectionDetails right until the feature will be implemented in this repo? Also, as I am in the need of using this quite often, I will be delighted to also contribute to the project.

Thank you very much!

Metaplex v2 Minting

I'm trying to replicate a metaplex v2 minting made with the metaplex js cli, here is a sample transaction: https://solscan.io/tx/2qgQRycQLf3mQi9QP1vMidod9XK1rWfhp9eDQss4ME1gFEuHVfWfDxuspsxdFBwf8no5xYj8Ly5H1MqZGntTbE8F?cluster=devnet

With the following solnet code I'm able to recreate it until the MintTo step:

var tokenAMint = new Account();
var fromAccount = new Account();
PublicKey associatedTokenAccount = AssociatedTokenAccountProgram.DeriveAssociatedTokenAccount(fromAccount.PublicKey, tokenAMint.PublicKey);
            
var transaction = new TransactionBuilder()

                .SetFeePayer(fromAccount)

                    SystemProgram.CreateAccount(
                        fromAccount,

                        fromAccount,
                        fromAccount))

                        fromAccount,
                        fromAccount.PublicKey,
                        tokenAMint.PublicKey))
                .AddInstruction(
                    TokenProgram.MintTo(

                    tokenAMint
                });

I am now stuck on calling the Metaplex NFT Candy Machine V2, I have not found the functionality to do this. Is it possible to do this with the current version of solnet.metaplex? Otherwise anyone has any suggestions, tips to implement it?

Update Metadata Account Fields

Hi. I was trying to update Metadata Account fields' value, but the following error shows up!
{"jsonrpc":"2.0","error":{"code":-32602,"message":"invalid transaction: Transaction failed to sanitize accounts offsets correctly"},"id":2}

Could you provide me a sample?

[Bug] MetadataAccount invalid parsing

Describe the bug
{"Specified argument was out of the range of valid values. (Parameter 'offset')"} exception in ParseData.

Reproduce
Create nft without creators but with primarySaleHappened.

Why
(binData.GetU16(MetadataAccountLayout.creatorsOffset) gives 256

MetadataAccountLayout creatorsOffset must be 321, not 322
creators is optional field.

Also, next fields missing

primarySaleHappened (not set)
isMutable (not set)
editionNonce (not set)
tokenStandard
collection
uses

P.S.
Current used manual deserializing is so bad, better use schema (like here), possible also code generator.

[Bug]MetadataCreate example is not working.

MetadataCreate example doesn't seems to work, both when trying to reproduce it on own codebase (getting Solnet.Metaplex from nuget) and cloning this repo.

NuGet version bump

Hello,

Is there going to be a NuGet version bump after @BifrostTitan' latest merges? Last one was #47, but the NuGet package was lastly updated 4 months ago.

He did way too many amazing things to not get that in the NuGet package manager.

Thanks a lot @BifrostTitan!

This is my code:
