Metamask RPC Runtime Errors: Troubleshooting Console Errors with Metamask
As you create your product listing/buy/sell form locally, it’s not uncommon to encounter errors along the way. A common error that pops up when using Metamask is the console message
RPC Error: [ethjs-query] while…. This error occurs due to a variety of reasons, such as incorrect network connection, invalid data, or issues with the Ethereum blockchain. In this article, we’ll dive deeper into the possible causes and solutions to resolve these errors.
Understanding RPC Errors in Metamask
Metamask is a popular Ethereum wallet that allows users to interact with the Ethereum network using Web3.js and JavaScript. When you initiate an RPC (Remote Procedure Call) transaction in Metamask, it sends a request to the Ethereum blockchain to perform various actions, such as depositing funds, updating account balances, or executing transactions.
The message
RPC error: [ethjs-query] while… indicates that there is a problem with the query execution. This error can occur for several reasons:
- Bad network connection: If you are not connected to the Ethereum network (i.e. the connection is lost), Metamask will throw this error.
- Invalid data: If the request contains invalid or malformed data, Metamask may reject it and display this error message.
- Ethereum blockchain issues
: Issues with the Ethereum blockchain can cause RPC errors.
Troubleshooting steps
To resolve these errors, follow these steps:
Step 1: Check your connection
Before attempting to execute an RPC transaction in Metamask, make sure that you are connected to the Ethereum network. You can do this by:
- Opening your MetaMask wallet.
- Clicking on the “Network” tab in the top right corner of the MetaMask window.
- Selecting either “Ethereum (mainnet)” or “Testnet”, depending on your preference.
Step 2: Validate your request
Before sending a request to Metamask, validate it to ensure that the data is correct and formatted correctly. You can use tools like
Metamask Inspector to inspect and test your requests.
Step 3: Check for Blockchain Issues
If you are experiencing RPC errors due to issues with the Ethereum blockchain, you may need to:
- Wait a while (e.g. 24-48 hours) to allow the blockchain to update.
- Use a different network or testnet, if available.
Step 4: Check your wallet configuration
Make sure your MetaMask wallet is configured and set up correctly. You can do this by:
- Checking your Metamask wallet settings in the MetaMask window.
- Ensuring you have the correct network and gas limits enabled.
By following these steps, you should be able to resolve RPC errors in Metamask and continue building your product listing/buy/sell form locally.
Conclusion
Metamask RPC runtime errors are common issues that can arise when using the Ethereum blockchain. By understanding the possible causes of these errors and implementing troubleshooting steps, you can effectively resolve them and ensure smooth interactions between your application and the Metamask wallet.
