Ethereum ethshers.js: Get empty results, despite existing transactions

When creating decentralized applications, monitoring of transactions is decisive for audit and ensuring the integrity of their intelligent contracts. One of the common problems with working with Blockchain Ethereum is getting empty results of "getLogs" despite existing transactions.

In this article, we will examine why you can see this behavior and how to solve it and resolve it using eéter.js.

Problem:

Getlogs returns to the log box that contains information on transactions on the Ethereum network. However, if there are no new or updated transactions to a specific address in a given period (also known as "Last Block" or "Block Number"), "Getlogs" will return an empty field.

Why can you see empty results

There may be several reasons why you see empty results of "Getlogs". Here are several possible causes:

1
Without new transactions

: If there are no new USDT broadcasts to wallet specific addresses within a given period, "getLogs" will not return any protocol.

• 
  Ancient Block Number : If the last block number is older than the block number you are interested in (for example, before 100 blocks), 'getlogs' may not return results because there is no New transactions that can be made load from this block.

• 
  Network overload or slow transaction processing
  
  
  
  : In a high traffic network, some transactions may be delayed or canceled, leading to empty protocols.

Steps to solve problems

Try the following steps to solve this problem:

1.

• 
  Set the right block limit : Increase your 'blocknumber' parameter when calling 'getlogs'. This forces the eetres

• 
  Use page : If there are many transactions in a specific period, consider using the pagination to get the results in parts. This can help you process larger data files more efficiently.

Example Code

Here is an example of a piece of code that demonstrates how to usegetlogs' with a pagination:

`JavaScript

Import * as "ether" eteros;

Constt Walletaddress = '0x ...'; // Replace the desired wallet address

CONST BLONMBER = 100; // Define an appropriate limit to load logs

ASSINNED FUNCTION GETLOGS () {)

Constant supplier = new ethshers.providers.web3Provider (window.ethereum);

to try {

CONST Logs = Wait Provider.getlogs ({{

Address: Walletaddress,

Blocknumber: blocknumber,

Fromblock: blocknumber,

Toblock: Infinity, // Load all transactions in the current block

});

Return protocols;

} Catch (error) {

Console.error (error);

return [];

}

}

// Call Getlogs with the pagination

Getlogs (). then (logs => console.log (logs));

`

According to these steps and using the page, you can solve the problem of obtaining empty "ghettogs" results despite existing transactions.
