INVALID_AUTH_KEY

Error Message : [Validation Code: INVALID_AUTH_KEY](panic: vm_error: Invalid transaction: Type: Validation Code: INVALID_AUTH_KEY)

When I run the token or transactions examples, here is the error info above.

Mainnet call error

example code

package main

import (
	"context"
	"fmt"
	"github.com/portto/aptos-go-sdk/client"
)

func main() {
	//client := client.NewAptosClient("https://aptos-mainnet.nodereal.io/v1/88215d0e3a944e46b367a9f8e5c0a965/v1")
	//client := client.NewAptosClient("https://fullnode.devnet.aptoslabs.com")
	client := client.NewAptosClient("https://aptos-mainnet.pontem.network/v1/")
	info, err := client.LedgerInformation(context.TODO())
	fmt.Println(info, err) //<nil> web_framework_error: not found
}

Misstype on type_tag.go

Named the struct TypeTagSinger instead of TypeTagSigner

'start' from GetTransactions should be uint64 to avoid overflow

As the current speed of testnet, version can quickly go over int32max
https://github.com/portto/aptos-go-sdk/blob/main/client/transactions.go#L13

start should be uint64, limit can be int or uint64

[debug] can not unmarshal transaction version 70214263

the type of event.data in transaction with version 70214263 is a string, but you claim all event.data as map[string]interface

edge case of getting address string from account address model

There is a bug when getting the address from the account address model.
Assume the address is 0x0111111111111111111111111111111111111111111111111111111111111111
The returned string would be 0x111111111111111111111111111111111111111111111111111111111111111
It is less than 1 character than the normal address because those 0 bytes after 0x prefix are trimmed.

Tranfert transaction issue

Hi guys,
First of all, thanks for developing an aptos sdk in golang. It really helps people like me :)

I ran into a problem while trying to do a simple transfer.
Here is my code...

func transfert(from utils.Account, to utils.Account, aptosValue uint64) error {
	accountInfo, err := aptosClient.GetAccount(ctx, from.Address)
	if err != nil {
		return err
	}
	addr, _ := models.HexToAccountAddress(to.Address)

	tx := models.Transaction{}
	err = tx.SetChainID(settings.ChainID).
		SetSender(from.Address).
		SetPayload(getTransferPayload(addr, aptosValue*settings.AptosUnit)).
		SetExpirationTimestampSecs(uint64(time.Now().Add(10 * time.Minute).Unix())).
		SetGasUnitPrice(settings.GasPrice).
		SetMaxGasAmount(uint64(settings.MaxGasPrice)).
		SetSequenceNumber(accountInfo.SequenceNumber).Error()
	if err != nil {
		return err
	}

	msgBytes, err := tx.GetSigningMessage()
	if err != nil {
		panic(err)
	}

	var pk1, _ = hex.DecodeString(from.PrivateKeyHex[2:])
	priv1 := ed25519.NewKeyFromSeed(pk1)
	signature := ed25519.Sign(priv1, msgBytes)
	var authErr = tx.SetAuthenticator(models.TransactionAuthenticatorEd25519{
		PublicKey: priv1.Public().(ed25519.PublicKey),
		Signature: signature,
	}).Error()
	if authErr != nil {
		panic(authErr)
	}
	rawTx, err := aptosClient.SubmitTransaction(ctx, tx.UserTransaction)
	if err != nil {
		panic(err)
	}

	utils.Log(utils.Info, 0, "Transfert 1 APTOS from "+from.Address+" to "+to.Address+" TX: "+rawTx.Hash)
	return nil
}

func getTransferPayload(to models.AccountAddress, amount uint64) models.TransactionPayload {
	return models.EntryFunctionPayload{
		Module: models.Module{
			Address: addr0x1,
			Name:    "coin",
		},
		Function:      "transfer",
		TypeArguments: []models.TypeTag{aptosCoinTypeTag},
		Arguments:     []interface{}{to, amount},
	}
}

As you can see, it is strongly inspired by your example script. The problem is that this part of the code triggers an error :

	msgBytes, err := tx.GetSigningMessage()
	if err != nil {
		panic(err)
	}

Output : panic: non-optional enum value is nil

I don't see what my script is missing to make it work. I hope you can help me understand the problem if there is one. Thanks in advance.

I change this mnemonic words generate invalid addresses

I use this bip39 standard to generate mnemonic words "heavy confirm beef vague prevent language panda scrub certain electric fix left" change to your mnemonic but those are invalid.
