Ethereum: getrawtransaction error? [Code -5]

Ethereum: Getting Raw Transaction Errors

Are you having trouble getting raw transaction data on your Ethereum network? You are not alone. Many users are having trouble reading raw transaction data due to an incorrect implementation of the getrawtransaction() method. In this article, we will investigate the cause and provide a solution.

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 use it incorrectly, resulting in errors like No information available about ....

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

• Invalid 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 If you pass an incorrect or outdated block hash, the function will return null.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 grouped into blocks with difficulty limits. If the transaction issue is not compatible with your network, the getrawtransaction() method may fail to retrieve transaction information.

Workaround: 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 given block or transaction.

Here is 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 the raw transaction information for a given contract. 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.

• Make sure your Ethereum network is compatible with the desired block or transaction weight level.

• If you are using a specific library or framework, check their documentation for guidelines on interacting with the 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 ....
