Failed to deserialize args?

[JatinSupra]

ISSUE SUMMARY: Failed to deserialize args Here:

 const transaction = await supraClient.createSerializedRawTxObject(
        new HexString(account.address().toString()),
        (await supraClient.getAccountInfo(account.address())).sequence_number,
        abi,
        "module_name
",
        "create",
        [
            new TxnBuilderTypes.TypeTagParser(coinType).parseTypeTag(),
            new TxnBuilderTypes.TypeTagParser(yCoinType).parseTypeTag()
        ],
        [
            BCS.bcsSerializeStr(name), //string
            BCS.bcsSerializeStr(symbol),
            BCS.bcsSerializeStr(image),
            BCS.bcsSerializeStr(description),
            website ? BCS.bcsSerializeStr(website) : new Uint8Array(), //Option<String>
            twitter ? BCS.bcsSerializeStr(twitter) : new Uint8Array(),
            telegram ? BCS.bcsSerializeStr(telegram) : new Uint8Array(),
        ]
    )

➥ SOLUTION SUMMARY:

An empty Uint8Array() fails because strings need a length prefix, and Option needs a first byte for Some or None.

maybe try this

const serializeOptionalString = (value: string | undefined): Uint8Array =>
    value ? BCS.bcsSerializeStr(value) : new Uint8Array([0]);
const transaction = await supraClient.createSerializedRawTxObject(
    ...previous code you had
    [
        BCS.bcsSerializeStr(name), // string
        BCS.bcsSerializeStr(symbol),
        BCS.bcsSerializeStr(image),
        BCS.bcsSerializeStr(description),
        serializeOptionalString(website), // Option<String>
        serializeOptionalString(twitter),
        serializeOptionalString(telegram),
    ]
);

IF This Gives, failed to deserialize arg error, Use this updated method for serializing the optional string

function serializeOptionalString(value: string | undefined): Uint8Array {
    if (value) {
        // Serialize `Some(value)`
        const serializedValue = BCS.bcsSerializeStr(value);
        return new Uint8Array([1, ...serializedValue]); // 1 for `Some`
    } else {
        // Serialize `None`
        return new Uint8Array([0]); // 0 for `None`
    }
}
