Describe your question in detail.

Hey there everyone!!!
I'm trying to perform signature verification, using go-sdk
For that i have deployed a contract with a method as
`#[view]
public fun verify(
message_hash: vector, signature: vector, pub_key: vector
): bool {
let signature_ed = ed25519::new_signature_from_bytes(signature);

    // Convert public key bytes to Ed25519 public key
    let public_key_ed = ed25519::new_unvalidated_public_key_from_bytes(pub_key);

    // Verify the signature using the message hash
    let is_valid =
        ed25519::signature_verify_strict(&signature_ed, &public_key_ed, message_hash);

    return is_valid
}`

Now when I'm invoking this method using ts-sdk it is working fine and result a true as an answer
`let msg = new MessageMoveStruct(
"Rkoranne0755",
onweAcc.accountAddress,
new Uint64(BigInt(25)),
[
  new Uint64(BigInt(1)),
  new Uint64(BigInt(2)),
  new Uint64(BigInt(3)),
  new Uint64(BigInt(4)),
  new Uint64(BigInt(5)),
]

);

let msgBytes = msg.bcsToBytes();
let msgHash = sha256(msgBytes);

console.log(msgHash);

let signedHash = signMessage(onweAcc.privateKey, msgHash);

const payload: InputViewFunctionData = {
function: ${onweAcc.accountAddress.toString()}::verify_signature::verify,
functionArguments: [
msgHash,
signedHash.toUint8Array(),
onweAcc.publicKey.toUint8Array(),
],
};

const result = await aptos.view({ payload });
console.log(result[0]);`

But when I'm trying to invoke the same method using go-sdk is giving me error saying failed to deseriealize the argument
`txMsg := utils.MoveMessageStruct{
Name: "Rkoranne0755",
Address: admin.Address,
Age: 25,
Storage: []uint64{1, 2, 3, 4, 5},
}
msgBytes := txMsg.Serialize()
msgHash := sha256.Sum256(msgBytes)

adminSignature, _ := utils.SignMessage(adminPrivateKey, msgHash[:])
pubKey, _ := bcs.Serialize(admin.PubKey())

err = utils.Verify(client, msgHash[:], adminSignature, pubKey)
if err != nil {
	fmt.Println("Error" + err.Error())
}`

What error, if any, are you getting?

Errorview function api err: HttpError POST "https://api.devnet.aptoslabs.com/v1/view" -> "400 Bad Request" "{"message":"PartialVMError with status FAILED_TO_DESERIALIZE_ARGUMENT","error_code":"invalid_input","vm_error_code":null}"

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

JUST SERIALIZE YOUR ARGUMENTS BEFORE SENDING THEM

// Step 8: Serialize data for verification
	addressBytes, err := bcs.Serialize(&admin.Address)
	if err != nil {
		panic("Error serializing address: " + err.Error())
	}
	amountBytes, err := bcs.SerializeU64(100)
	if err != nil {
		panic("Error serializing amount: " + err.Error())
	}
	serializedMsg, err := bcs.SerializeBytes(signedMsg)
	if err != nil {
		panic("Error serializing signed message: " + err.Error())
	}
