Ethereum: Error Message Explained – “TypeError: unsupported addressable value (argument=”target”, value=null, code=INVALID_ARGUMENT, version=6.11.1)”
As a developer who recently deployed your Ethereum-based smart contracts locally using Hardhat, you may have encountered an error message that seems daunting and confusing. In this article, we will analyze the error message “TypeError: unsupported addressable value (argument=”target”, value=null, code=INVALID_ARGUMENT, version=6.11.1)” so that you understand what it means and how to fix the problem.
What does the error message mean?
The error message is a technical description of the problem you are experiencing on your machine. Here is a breakdown:
- “TypeError”: This is an error type that occurs when a function expects an argument but receives one instead.
- “unsupported addressable value (argument “target”, value=null)”: This indicates that the getWeth.js script is attempting to use an Ethereum wallet as an “address” to send Ether, but is not doing so correctly. The “null” value represents a missing or invalid argument.
(code=INVALID_ARGUMENT, version=6.11.1): This additional information provides more details about the problem:
+ “INVALID_ARGUMENT”: This error occurs when a function expects an argument that is invalid for its purpose.
+ “version=6.11.1”: This indicates the version of the Ethereum Solidity compiler used to compile the contract code.
Why is this error occurring?
There are several possible reasons why this error may occur:
- Missing or incorrect wallet name: You may have created a script that expects an Ethereum wallet address, but it is not configured or set up correctly.
- Invalid or missing getNamedAccounts function call
: The getNamedAccounts function is used to get the accounts associated with your Ethereum wallet. If this function is not called correctly or you are trying to access an account that does not exist, errors like this may occur.
- Incorrect contract deployment: Make sure your smart contracts are deployed correctly and have the correct addressable values.
How to resolve the issue
To resolve the error message, follow these steps:
- Check wallet address
: Make sure you are using a valid Ethereum wallet address in your script. Check that the address is spelled correctly and matches the address associated with your wallet.
- Check the getNamedAccounts function call: Make sure the getNamedAccounts function is called correctly and the correct accounts are retrieved. Make sure you pass the required arguments to this function (e.g. “address”, “from”).
- Check contract deployment: Make sure your smart contracts are deployed correctly with the required addressable values. Check the code for errors or inconsistencies.
Example fix
Here is an example of how you can change your script to fix the problem:
const { getNamedAccounts, ethers } = require("hardhat");
const accounts = await getNamedAccounts({ from: "your wallet address" });
const contractAddress = accounts[0].contract;
// Verify that the contract was deployed correctly with the correct addressable values.
console.log(ContractAddress: ${contractAddress});
By following these steps and examples, you should be able to resolve the error message and successfully deploy your Ethereum-based smart contracts locally using Hardhat.
