Metamask Installation Error: Not enough Ethereum Ethers
When trying to connect your contract to the Rinkeby network using Infura in the browser, one of the most common problems is the console.log
operator, which displays undefined
when requesting access to ethers
. This error is usually caused by an incompatible environment or configuration.
In this article, we will look at the causes and solutions to this problem, focusing on how to solve it with Metamask as an Ethereum injection provider in your browser.
Understanding the problem
The main reason for this error is the way console.log statements are handled when interacting with web3 providers such as Infura. When you call loggers.ethereum
, the JavaScript environment does not automatically pass an Ethereum instance to the console logging operator due to differences in how these functions are called and executed.
The Metamask Problem
Metamask, a popular provider of Ethereum wallets, is intended for use as an injection provider for contract deployment. When you use metamask-injection
with Infura, it injects your deployed contract instance into the browser context. However, if this process incorrectly initializes or configures the ethers
module, you may encounter problems similar to the ones described.
Troubleshooting Steps
To resolve the undefined
issue in the console log statement, follow these steps:
Step 1: Check Metamask installation
First, make sure your MetaMask installation is done correctly. You must have a working MetaMask wallet installed and correctly configured in your browser.
Step 2: Configure the Infura provider
Make sure you are using the correct provider for your Ethereum network (e.g. Rinkeby) in the metamask-injection
configuration:
const providers = {
info: {
apiKey: "YOUR INFURA API KEY",
network: "rinkeby"
}
};
// Using the injector to deploy the contract and connect it using the MetaMask injection
injector.deploy(
contractName,
contractabi,
providers.infura
);
Step 3: Checking the initialization of the Ethers module
Make sure you initialize the ethers
module correctly in your code. Here is an example of how to do it:
// After setting up the MetaMask injection, make sure ethers are initialized correctly
const ethers = require('ethers');
// Example of deployment and initialization of the contract
const MyContract = artifacts.require("MyContract");
contract('My Contract', function (accounts) {
it('should deploy and initialize the contract', async () => {
const deployedContract = await MyContract.deployed();
console.log(Contract deployed at ${deployedContract.address}
);
// Make sure the ethers module is initialized correctly
console.log(ethers);
// You can now use ethers to interact with the deployed contract instance
});
});
Step 4: Update the MetaMask injection configuration
Make sure that the infura
provider in your metamask-injection
configuration points to the correct Ethereum network (e.g. Rinkeby):
const providers = {
info: {
apiKey: "YOUR INFURA API KEY",
network: "rinkeby"
}
};
// Using the injector to deploy the contract and connect it using the MetaMask injection
injector.deploy(
contractName,
contractabi,
providers.infura
);
Step 5: Verify the initialization of the Ethers module after deployment
Finally, verify that your deployed contract instance has been properly initialized after deployment:
“`javascript
// Example of deployment and initialization of the contract
const MyContract = artifacts.
