Ethereum: getrawtransaction error? [Code -5]

Ethereum: Getting Raw Transaction Errors

Are you experiencing issues with getting raw transaction data on your Ethereum network? You’re not alone. Many users are struggling to read raw transactions due to an incorrect implementation of the getrawtransaction() method. In this article, we’ll delve into the cause and provide a solution.

The Problem: Incorrect Implementation of getrawtransaction()

getrawtransaction() is a built-in Ethereum API function that retrieves information about a specific block or transaction. However, some users are using it incorrectly, leading to errors like No information available about ....

To understand why this error occurs, let’s first examine the possible causes:

• Incorrect Block Hash: The getrawtransaction() method requires a valid block hash as an argument. If you pass an incorrect or outdated block hash, the function will return null.

• Transaction Difficulty: Ethereum transactions are batched together into blocks with difficulty constraints. If the transaction difficulty is not compatible with your network, the getrawtransaction() method may fail to retrieve information about the transaction.

The Solution: Use eth_getTransactionCount() Instead

To avoid these errors, you can use a more reliable approach using eth_getTransactionCount(). This function returns the number of raw transactions available for a specific block or transaction.

Here’s an example:

const txs = await ethers.getContractRawTransaction("0x...Your Contract Address...");


// Get the total number of raw transactions

txCount = await txs.getTransactionCount();


console.log(txs, txCount);

In this code, eth_getContractRawTransaction() retrieves a specific contract’s raw transaction data. We then use eth_getTransactionCount() to get the total number of raw transactions available for that contract.

Additional Tips

• Make sure you have the latest version of the Ethereum Web SDK installed.

• Verify that your Ethereum network is compatible with the desired block or transaction difficulty level.

• If you’re using a specific library or framework, check its documentation for guidance on interacting with Ethereum APIs.

By following these steps and tips, you should be able to successfully retrieve raw transaction data without encountering errors like No information available about ....
