Unable to Retrieve USDT Balance from TON Mainnet

[lxxxxxxi]

Description

I attempted to retrieve the USDT balance from the TON mainnet using the master contract address EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs. I confirmed that I obtained the correct jetton wallet address. However, I encountered the following error:

async getBalance(provider: ContractProvider) {
    const { stack } = await provider.get("get_wallet_data", []);
    console.log(stack);

    return fromNano(stack.readBigNumber());
}

When using the same method to connect to the testnet wallet and the testnet token address, I can successfully retrieve the balance without any errors.

Expected Behavior

The balance should be successfully retrieved from the TON mainnet without any errors, similar to how it works with the testnet.

Actual Behavior

An error occurs when attempting to retrieve the balance from the TON mainnet.

Additional Information

• The testnet wallet and token address work correctly with the same method.
• The mainnet setup has been verified to use the correct jetton wallet address.

Environment

• TON mainnet
• Master contract address: EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs
