Solana: SolanaJSONRPCError: failed to get transaction: invalid signature

Troubleshooting the “Invalid Signature” Error Using the Solana Web3 Library

Error: “JSONRPCEror: Failed to retrieve operation”! This is a common issue when interacting with Solana blockchain nodes using the Web3 library. In this article, we will look at how to resolve this error and troubleshoot common issues.

What is JSONRPCE error: Failed to retrieve operation?

This error occurs when the JSONRPC interface on a Solana node returns an invalid response to a request sent by your JavaScript application to the Solana network. The error typically indicates that:

• Your client-side JavaScript code does not have the necessary permissions or authorization to access certain data.

• There are issues with the requested operation (e.g. incomplete, signature mismatch, etc.).

How ​​to fix this error from Solana Web3 library?

To resolve this error, follow these steps:

1. Make sure you have the correct permissions

Make sure your JavaScript application is requesting the necessary permissions to access data on the Solana network. You can find the available permissions in the solana.js documentation.

const solanaTransactionPermissions = await SOLANA_CONNECTION.getTransactionsPermissions();
console.log(solanaTransactionPermissions);

2. Verify that the operation completed

Verify that the requested transaction completed successfully by checking the “confirmed” property of the response received from the Solana blockchain node.

const receipt = await SOLANA_CONNECTION.getTransaction(txHash, { commit: 'committed' });
if (!receipt.confirmed) {
console.log("The operation has not been confirmed yet.");
} else {
console.log("The operation has completed.");
}

3. Check for signature issues

If the transaction signature matches the expected client code signature, make sure to use the correct “signature” property in the request.

const Receipt = await SOLANA_CONNECTION.getTransaction(txHash, { commit: 'committed', maxSupportedTransactionVersion: 0 });
if (receipt.signature !== 'expected_signature') {
console.log("Signature mismatch. Please review your code.");
} else {
console.log("The signature is valid.");
}

4. Check the transaction response

Take a closer look at the response to the operation to identify any issues. Look for errors like “Invalid signature” or “Failed to receive transaction”.

const receipt = await SOLANA_CONNECTION.getTransaction(txHash, { commit: 'committed' });
if (receipt.error) {
console.log(receipt.error.message);
} else if (receipt.date) {
// Process the transaction data here.
}

5. Check for network errors

Make sure your Solana node is running a stable and up-to-date version and that any network issues have been resolved.

const solanaNode = await SOLANA_CONNECTION.getNode();
if (!solanaNode) {
console.log("Solana node not found.");
} else {
console.log(solanaNode);
}

After following the steps below and fixing the error in your code, you should be able to resolve the Solana Web3 library “Invalid Signature” error. If the issue persists, please provide more information about your specific use case and related error messages for further assistance!
