Troubleshooting Guide for MetaMask RPC Error: The user has not authorized the requested account or method
As a MetaMask user, it is critical to understand how to troubleshoot errors that occur when interacting with the Ethereum blockchain. A common issue encountered is an “RPC error” when attempting to encrypt sensitive data using MetaMask. In this article, we will walk you through the steps to resolve this error.
Understanding the RPC Error
When a user attempts to perform an action on the Ethereum network using the MetaMask web interface or dApp (decentralized application), they are prompted to authorize the requested account and method. If the user denies permission, the request fails and an “RPC error” occurs.
The code snippet for the request
Let’s examine the code snippet you provided:
let encryptedPublicKey;
await window.ethereum.request({
method: 'eth_getEncryptionPublicKey',
params: [account1], // You must pass the account address here
});
In this example, account1 is an Ethereum account address. The error occurs because you are not providing a valid account that MetaMask will request authorization for.
RPC Error Resolution
To resolve the issue, follow these steps:
1. Check MetaMask Settings
Make sure your MetaMask account is set as the default wallet and has the «Allow wallet access» option enabled.
2. Check Ethereum Network Connection
Make sure you are connected to a supported Ethereum network (e.g. Mainnet, Rinkeby).
3. Update the Web3.js library
If you are using an outdated version of the Web3.js library, update it to the latest stable version using npm or yarn:
npm install web3@latest
or
yarn add web3@latest
4. Check your account permissions
Make sure you have sufficient permission levels on the Ethereum network:
active– You are currently logged in and authorized.
admin– MetaMask has administrative privileges, allowing it to perform actions without user interaction.
If you’re still having issues after updating your Web3.js library and checking your MetaMask configuration, try the following:
5. Inspect the error message
Check the console output for relevant details that might indicate the source of the error:
{
"code": 100000001,
"status": 0,
"data": {
"method": "eth_getEncryptionPublicKey",
"params": [
"0x...your_account_address..."
],
"transactionHash": "",
"gasPrice": "",
"nonce": ""
},
"input": {
"address": "0x...account_address...",
"key": "0x...key..."
}
}
Identify the specific error code (e.g.
English:e.g. 100000001) and check if it is related to your account or method.
Additional troubleshooting steps
If you are still experiencing issues, please try the following:
- Check that MetaMask is configured correctly in your wallet provider’s settings.
- Make sure the network is supported by your version of MetaMask (e.g. Web3.js v1.7.4).
- If you are using a browser extension, please restart it and refresh the page after updating the Web3.js library.
By following these steps, you should be able to resolve the «RPC Error» when trying to encrypt sensitive data with MetaMask.
