Error: It is not possible to call an ‘recording’ function in an Ethereum contract using Ethers.js
When working with intelligent contracts at Blockchain Ethereum, it is common to use tools like Ethers.js to interact with contract instances. However, there is a crucial step that many developers ignore in creating their first Ethereum contracts using Ether.js.js methods: calling in the contract instance.
In this article, we will explore why you can find an error when trying to call an Write function in an Ethereum contract using eter.js and provide guidelines on how to solve it.
The question:
When you declare an instance of the contract on your local hardhat network using the following code:
`JavaScript
CONST 0 = “0XAC0974BEC39A17E36BA4A6B4D238FF944BACB478CBED5EFCAE784D7BF4FF80”;
`
You are creating a new instance of an Ethereum contract. However, Ethers.JS does not automatically record the contract on the Ethereum network. To interact with a contract on your local hardhat network, you need to call your methods and use the call function of Ethers.js.
The solution:
To correct this problem, you can add the following code before calling any method in the contract instance:
`JavaScript
Contract = New Contract (Account0);
`
This creates a new contract instance using the address of the account provided. You will also need to call the “Call” function of Ethers.js to execute method calls at the contract instance.
Example Code:
Here is an up -to -date example of how you can declare an instance of the contract and call your methods using Ethers.js:
`JavaScript
Consta {ethorers} = requires (“hardhat”);
// Define the ABI (Binary Interface of the Application) Contract)
CONST ABI = [
{
Inputs: [],
STATEMUTABILITY: “VIEW”,
Type: “Function”
},
{
Inputs: [“string”, “int”, “boolean”],
STATEMUTABILITY: “WRITE”,
Type: “Function”
}
];
// Create a new contract instance using hardhat
ASSINCRONE FUNCTION MAIN () {
CONST 0 = “0XAC0974BEC39A17E36BA4A6B4D238FF944BACB478CBED5EFCAE784D7BF4FF80”;
Constinstinance = awaits ethhers.getContractory (“YourcotractName”);
CONTT CONTRACT = awaits contractinstance.deplay (Account0);
// Call a method in the contract instance
Consta result = awaits contract.methods.yourmethod (). Call ();
console.log (result); // Output: its return value
// Delete the contract instance
wait for contract.Destroy ();
}
// performs the main function using hardhat
main();
`
Conclusion:
In this article, we highlight an essential step in interacting with intelligent contracts in the Blockchain Ethereum using Ethers.js. By creating a new instance of the contract and calling your methods, you can perform multiple actions on your local hardhat network.
Remember to update your code agreement to use the Contrastinence variable in all its function. Happy coding!
