Metamask Transaction Error: Resolving “Could not clone function object”

As a MetaMask user, you are probably already familiar with the process of sending transactions and interacting with the MetaMask interface. However, sometimes you may encounter issues when trying to sign transactions or perform actions on your wallet. One common error you may encounter is the “Could not clone function object” error.

In this article, we will take a closer look at what is happening behind the scenes, discuss possible solutions, and provide tips on how to resolve the Metamask transaction error.

What does the “Could not clone function object” error mean?

When you try to sign a transaction using MetaMask, an instance of the Function constructor is created, which represents the function that is to be called. However, this instance must be cloned before it can be used as a contract or run on the Ethereum Virtual Machine (EVM). The problem lies in the way instances are created and cloned.

Error “Function object could not be cloned”

If you encounter this error:

• It means that MetaMask is trying to create an instance of Function that already exists as a local variable. This happens when you use new Function() directly.

• The Function constructor must be cloned before it can be used. However, since instances are not cloned properly, this creates a problem.

Causes and Solutions

The main causes of the “Could not clone function object” error in MetaMask are:

• Insufficient DOM access: If you try to create an instance of Function directly, without a valid DOM element (e.g. without document etc.), MetaMask will throw an error.

• Incorrect use of new Function(): When using new Function(), it is important that the return value is a string, not the function object itself.

Solution

To fix this issue and create valid Function instances:

• Before trying to use new Function(), make sure you have a valid DOM element (document).

• Save the returned value as a string, not as an instance:

const contractCode = 'function add(a, b) { return a + b; }';

• You can also save your code to a file or object and then execute it using MetaMask:

const contractCodeFile = './contract.js';
// Import the contract code
import the contract from contractCodeFile;
// Create an instance of the function with the contract code
const functionInstance = new Function('return ' + contract)(null, null);
// Now you can use the function as a contract or execute it

Additional tips and notes

• To reduce the risk of similar issues, always keep your MetaMask session running for a longer period of time.

• If you are working on a large project with many functions, consider using async/await instead of new Function():

const asyncFunction = async (a) => {
return a + b;
};
// Use async function as needed in your code

In summary, “Cannot clone function object” errors are a common issue when trying to sign transactions or interact with MetaMask. By understanding the cause of the issue and implementing the necessary solutions, you can resolve the issue and continue working efficiently on your Ethereum-based projects.

Usage Example

Let’s say you’re building an application that requires sending transactions to multiple Ethereum addresses using Metamask. When trying to sign a transaction for each address separately, you might get an error saying “Cannot clone function object”:

“`javascript

const metamask = require(‘metamask’);

// Get a MetaMask connection

const connection = await metamask.connect();

// Instantiate a function with each contract code

for (let i = 0; i < contracts.
