I am new to Smart Contracts. I am unable to read a smart contract from Binance test network. I keep getting an Unhandled Rejection every time I attempt to read my smart contract using ethers.js.
Error
Unhandled Rejection (Error): invalid fragment object (argument="value", value=[{"inputs":[{"internalType":"address","name":"_owner","type":"address"},{"internalType":"string","name":"_name","type":"string"},{"internalType":"string","name":"_sr_number","type":"string"},{"internalType":"string","name":"_branch","type":"string"},{"internalType":"string","name":"_date","type":"string"},{"internalType":"string","name":"_grade","type":"string"}],"stateMutability":"nonpayable","type":"constructor"},{"inputs":[],"name":"branch","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"date","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"getName","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"grade","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"name","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"owner","outputs":[{"internalType":"address","name":"","type":"address"}],"stateMutability":"view","type":"function"},{"inputs":[],"name":"sr_number","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"}], code=INVALID_ARGUMENT, version=abi/5.0.13)

let provider = ethers.getDefaultProvider();
let contractAddress = "0x60aD9FCD26092de54CDF3Ff83900a5B5a52887Ab";
let contract = new ethers.Contract(contractAddress, abi, provider);
let currentValue = await contract.getName();
alert(currentValue);
};
My solidity file
pragma solidity ^0.8.0;
contract FactoryContract {
address public owner = msg.sender;
address [] public createdContracts;
event ContractCreated(address contractAddress);
function createContract(string memory _name, string memory _sr_number, string memory _branch, string memory _date, string memory _grade) public {
address newContract = address(new Contract(msg.sender, _name, _sr_number, _branch, _date, _grade));
emit ContractCreated(newContract);
createdContracts.push(newContract);
}
function getDeployedContracts() public view returns (address[] memory)
{
return createdContracts;
}
function getOwner() public view returns (address)
{
return msg.sender;
}
}
contract Contract {
address public owner;
string public name;
string public sr_number;
string public branch;
string public date;
string public grade;
modifier onlyOwner() {
require(msg.sender == owner);
_;
}
constructor (address _owner, string memory _name, string memory _sr_number, string memory _branch, string memory _date, string memory _grade) {
owner = _owner;
name = _name;
sr_number=_sr_number;
branch = _branch;
date = _date;
grade = _grade;
}
function getName() public view returns (string memory)
{
return name;
}
}
Where am I going wrong? I have deployed the contracts using a factory contract. I've used the ABI of the contract and not the ABI of the factory contract.
