Error while Sending Transaction

[memxor]

Describe your question in detail. For example how do you get all transactions for a user with the TypeScript SDK?

I'm getting the mentioned error while trying to Send a Transaction. My game was previously on Randomnet, but since it has been shut down, I moved the project to Devnet, and after moving it to devnet I'm getting this error.

What error, if any, are you getting?

{"message":"parse request payload error: failed to parse "string(U64)": invalid type: null, expected a string (occurred while parsing "UserTransactionRequestInner") (occurred while parsing "EncodeSubmissionRequest")","error_code":"web_framework_error","vm_error_code":null}

What have you tried or looked at? Or how can we reproduce the error?

I tried finding solutions online but couldn't find any. I've debugged the string I'm sending and have found no errors in that, and it is not null.

Which operating system are you using?

Linux (Ubuntu, Fedora, Windows WSL, etc.)

Which SDK or tool are you using? (if any)

Unity SDK

Describe your environment or tooling in detail

Hi @memxor could you share a code snippet?

Hi, yeah sure, here, I get a ProtocolError 400

byte[] bytes = "3e79e6c4f4d55299f09b3aef9a8ba33a2ba0f53d081336c3811c3e4712a8d48b".ByteArrayFromHexString();
Sequence sequence = new(new ISerializable[] { new BString(username) });

EntryFunction payload = new(
    new(new AccountAddress(bytes), "aptos_horses_user"),
    "create_user",
    new(new ISerializableTag[] { }),
    sequence
);

Transaction createUserTx = new();
Coroutine createUser = StartCoroutine(RestClient.Instance.SubmitTransaction((_transaction, _responseInfo) =>
{
    createUserTx = _transaction;
    responseInfo = _responseInfo;
},
WalletManager.Instance.Wallet.Account,
payload));
yield return createUser;

if (responseInfo.status != ResponseInfo.Status.Success)
{
    Debug.LogError("Cannot create user. " + responseInfo.message);
    yield break;
}

Debug.Log("Transaction: " + createUserTx.Hash);
Coroutine waitForTransactionCor = StartCoroutine(
    RestClient.Instance.WaitForTransaction((_pending, _responseInfo) =>
    {
        responseInfo = _responseInfo;
    }, createUserTx.Hash)
);
yield return waitForTransactionCor;
