Metamask edition in Reactjs with Web3Js and Metamask
As a developer who works with ReactJS V18.2 and Web3.JS V1.8 for blockchain interactions, I found a common problem with Metamask integration: “Error: Record after the end.” In this article, we will explore the cause of this error, its effects on our application and provide solutions to solve it.
The question
When working with Metamask, Web3.JS expects a transaction to be fully performed before writing to Blockchain. However, sometimes execution is interrupted due to various reasons such as network problems or user input. As a result, we can find an “error: record after final” error by trying to send transactions.
Causes of the question
There are several causes that can lead to this problem:
- User input : When a user inserts its metamask password, it can block subsequent requests due to safety reasons.
- Network Questions : A temporary network delay or disconnection can cause the transaction to be interrupted before it is fully performed.
- Timeouts
: If we do not set a time limit to send transactions, they can limit time and leave us an “error: record after final” error.
Effects on our application
To understand how this problem affects our application:
- When users try to send transactions to the test server, the “Error: Recording after final” error will prevent them from filling in their transaction.
- On the main server, which is connected to the same blockchain instance as the test server, we can find similar problems due to network latency or user input.
Solutions
To solve this problem and ensure a soft user experience:
- Implement errors handling : We need to deal with the “Error: Recording after final” error, implementing attempt mechanisms or time limit for sending transactions.
- Set the timer to send transactions : Set the timer to wait before sending transactions, ensuring that they are not interrupted by user inputs or network problems.
- Use a new attempt mechanism with web3.js : Consider using a library like
Web3JS-Retristyto repeat failure transactions, reducing the number of errors” Error: Record after the end “.
Example Code
Here is an example of code code that demonstrates how to deal with the error “Error: Record after final”:
`JavaScript
Import {eetres} of ‘eetres’;
Import * as web3 of ‘Web3’;
CONSTT CONTRACT = new ethers.contract (‘0x …’, Web3, {mainnet: True});
Sendtransaction function () {
to try {
Constt Transaction = Wait Contract.Createtransaction ({
To: ‘0x …’,
Value: ‘0.01 ether’,
Gasmimit: ‘10000000’,
GASPRICE: ‘20000 GWEI’
});
Const Txhash = Wait Contract.Sendtransaction (Transaction);
console.log (transaction sent successfully: $ {txhash});
} catch (error) {
IF (Entrance Error Instance.Walleterror) {
Console.error (‘Wallet Error:’, Error.Message);
} else if (error error instance) {
console.error (‘error:’, error);
}
}
}
CONST INTERVALID = SETINTerval (Sendtransaction, 10000);
// Works to call Sendtransaction every minute
Checkforsen Function () {
Clearinterval (interval);
Sendtransaction ();
}
Setinterval (CheckForsend, 60000); // Send transactions every hour
`
By implementing error handling and using an attempt mechanism with Web3JS-Retristy, we can ensure that our application remains stable even in the presence of network problems or user input.
