Example code does not work (syntax error)

[esigra]

The example code at https://github.com/ton-community/ton-contract-executor does not work:

    let code = Cell.fromBoc(state.code!)[0]
                                  ^^^^

SyntaxError: missing ) after argument list

[esigra]

The following code almost works (it hangs at the end, don't know how to fix it):

import {Address, Cell, TonClient} from "@ton/ton";
import {SmartContract} from "ton-contract-executor";

const contractAddress = Address.parse('EQD4FPq-PRDieyQKkizFTRtSDyucUIqrj0v_zXJmqaDp6_0t')

const client = new TonClient({
    endpoint: 'https://toncenter.com/api/v2/jsonRPC'
})

const state = await client.getContractState(contractAddress)
const code = Cell.fromBoc(state.code)[0]
const data = Cell.fromBoc(state.data)[0]

const contract = await SmartContract.fromCell(code, data)

const res = await contract.invokeGetMethod('seqno', [])
console.log(res)

Found how to not hang at the end: TvmRunnerAsynchronous.getShared().cleanup()

Getter function in Tact syntax
for example
get fun sum(a: Int, b: Int): Int {
return a + b;
}
get fun and(a: Bool, b: Bool): Bool {
return a && b;
}
get fun answer(a: Int): String {
let sb: StringBuilder = beginString();
sb.append("The meaning of life is ");
sb.append(a.toString());
return sb.toString();
}
Can only pass int type? Why is there an error in the address type?
for example
get fun getBalance(adr:Address) :Int {
//Check the user's balance
return 0;
}
Unable to execute get method. Got exit_code:
