get USDT balance of an address

[m0x61h0x64i]

Hi, i tried this code to get the USDT balance of an address:

const contractAddress = 'TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t'
const { abi } = await tronWeb.trx.getContract(contractAddress)
let contract = await tronWeb.contract(abi.entrys, contractAddress)
const balance = await contract.methods.balanceOf('THpjKwQAPEGHG715fLB49NbH8ZvPtGs7Z6').call()
console.log(balance)

but it shows error:

node:internal/process/esm_loader:97
    internalBinding('errors').triggerUncaughtException(
                              ^
class java.security.InvalidParameterException : owner_address isn't set.
(Use `node --trace-uncaught ...` to show where the exception was thrown)

Node.js v18.17.0

whats the problem? @summertanh

It seems like you called a javatron service without providing an owner_address. Maybe the error was note thrown from here?
