Error: Can’t be called ‘Write’ feature on Ethereum Agreement using Ethers.Js
When working with smart contracts on the Ethereum Blockchain, it is customary to use tools such as Ethers. However, creating your first Ethereum contracts using Ethers.Js: Calling methods in the Agreement Instance is an important step that many developers ignore.
In this article, we will study why you could face an error trying to call the “writing” function to the Ethereum contract using Ethers.Js, and give instructions on how to resolve it.
Question:
When you declare a contract in a local Hardhat network using the following code:
`JavaScript
CONST account0 = “0xac0974bec39a17e36ba4a6b4d238FF94478CBed5EFed5EFCAE784D7BF4F4F2FF80”;
`
You are building a new case of Ethereum. However, Ethers.Js does not automatically register a contract with the Ethereum network. In order to interact with the local hardhat network, you need to call its methods and use the “Call” function from Ethers.Js.
Solution:
You can add this code before calling this problem to the contract:
`JavaScript
Contract = new contract (account0);
`
This creates a new case of the contract using the specified account address. You will also need to call the “Call” feature from Ethers.Js to fulfill the method of calls to the contract instance.
Code:
Here is an updated example of how you can declare a contract case and call its methods using Ethers.Js:
`JavaScript
Const {ethers} = ask (“Hardhat”);
// Define the contract both (application binary interface)
Const both = [
{
Inputs: [],
Statemutability: “See”,
Type: “Function”
},
{
Inputs: [“string”, “int”, “bull”],
Statemutability: “Write”,
Type: “Function”
}
];
// Create a new contract with Hardhat
ASYNC Function Main () {
CONST account0 = “0xac0974bec39a17e36ba4a6b4d238FF94478CBed5EFed5EFCAE784D7BF4F4F2FF80”;
Const Consterinstance = Expect Ethers.GetContectFactory (“YourcontactName”);
Const Agreement = Expect a contractor.dloy (account0);
// Call the Agreement Instance Method
Const result = wait for the contract.ethods.yourmethod (). Call ();
Console.log (result); // Output: Your return value
// Delete the Agreement Instance
wait for the contract.destoy ();
}
// Run the main feature using Hardhat
main ();
`
Conclusion:
In this article, we have emphasized an important step in interacting with smart contracts on Ethereum Blockchain using Ethers.Js. By creating a new contract and calling its methods, you can take a variety of activities on the local hardhat network.
Remember to update your code accordingly to use the “Contractinstance” variable throughout the function. Happy encoding!
