Resolution of the error “non -valid signature” with the Solana Web3
library **
The error “JSONRPCERROR: Founded transaction” error! This is a common problem when interacting with the Blockchain Solana nodes using the Web3 library. In this article, we will explore how to solve this error and solve common problems.
What was JSONRPCERROR: failed to get the transaction?
This error occurs when the JSONRPCinterface on a Solana node returns an unlikely request for your JavaScript program to the Solana network. The error generally indicates that:
- Your JavaScript Customer Code does not have the authorizations or authorizations necessary to access certain data.
- There are problems with the transaction interviewed (for example, it is not finalized, has a signature discrepancy, etc.).
How to resolve this error in the Solana Web3 library?
To resolve this error, follow these steps:
1. Make sure you have correct authorizations
Make sure your JavaScript program requests the authorizations necessary to access data on the Solana network. You can list the authorizations available in the “Solana.js” documentation.
Javascript
Const SolanransActionpertmissions = Await Solana_Connection.gettransactions PERMISSIONS ();
console.Log (SolanransActionPermissions);
'
2. Check that the transaction was finalized
Check if the transaction you are trying to question has been successfully finalized by checking its "confirmed" property in the response of your Blockchain Solana node.
Javascript
Const Receip = wait solana_connection.gettransaction (txhash, {engagement: 'finalized'});
if (! Receipt.confirmed) {
console.log ("The transaction is not yet confirmed.");
} other {
Console.log ("The transaction was finalized.");
}
'
3. Check signature problems
If the transaction signature corresponds to the expected signature of your customer code, be sure to use the correct "signature" property in your request.
Javascript
Const Receip = wait solana_connection.gettransaction (txhash, {engagement: 'finalized', maxsupportedtransAction Ver: 0});
If (Receipt.Signature! == 'Your_expect_Signature') {
Console.log ("Signature adopter. Please consult your code.");
} other {
console.log ("signature is valid.");
}
'
4. Inspect the transaction response
Take a closer look at the transaction response to identify any problem. Look for errors such as "non -valid signature" or "impossible to obtain the transaction".
Javascript
Const Receip = wait solana_connection.gettransaction (txhash, {engagement: 'finalized'});
If (Receipt.error) {
Console.log (Receipt.error.esage);
} else if (receipt.data) {
// Process the transaction data here.
}
'
5. Check network errors
Make sure your Solana node works on a stable and up-to-date version, as well as network problems have been solved.
Javascript
Const Solananode = wait solan_connection.getnode ();
If (! Solananode) {
Console.log ("Solana node not found.");
} other {
Console.log (solananode);
}

By following these steps and by troubleshooting the error in your code, you should be able to resolve the “non -valid signature” error of the Solana Web3 library.
