Solana JSONRPC Error Solution: Failed to reach a transaction with invalid signature
False error “Invalid Signature”! This problem can occur if you use Solana Web3 library in JavaScript applications. In this article, we will look at you how to solve this error and get a deal from Solana JSON-RPC API.
What is JSONRPERROR: Failed to get a transaction: Invalid signature?
When you call “Solana_Connection.Gettransaction (Txhash, {Commitment:” Complete “, Maxsupportedtransaction: 0})if the deal has an invalid signature, the library will throw in the JSONRPERROR.
JSON
{
“Error”: {
“Code”: “Invalididsignature”,
“Message”: “Invalid Signature”
}
}
`
Why is this happening?
There are several reasons why you could face an invalid signature error. Here are some possible causes:
1
Deal with zero version : If the transaction has a maxsupportedtransactionVersion of 0, Solana Json-RPC API will show the error.
- Invalid or missing liabilities : Make sure all the necessary liabilities (eg "complete", "approved", etc.) are present and valid.
3
The Hash Questions : Check that the transaction you use is correct.
Error resolution
Follow these steps to solve this error:
1
Check the transaction version : Make sure you "MaxSupportedTransactionVersion" is set to a value that is not zero. You can find more information on the available versions in the [Solana Documentation] (
- Check transactions : Check your file “Solana.Json (or equivalent) to make sure all the necessary obligations are and valid.
3
Update the deal has Hash
: If you are using a new or updated version of Solana, update the deal has to have been in your code.
Example of resolution
`JavaScript
Const Solana = ask (‘(Solana’);
// Create Solana Connection
Const Connection = New Solana.connection (Solana.Key.Key.fromuint32array (New uint8array ([0x01, 0x02, 0x03]), ‘Mainnet-beta-1’);
Try {
// Get a deal hash
Const Txhash = Expect Connection.Gettransaction (‘Your_transaction_hash_here’, {commitment: ‘complete’}). ID;
// Process the transaction
Console.log (transaction ID: $ {txhash.id});
} Catch (error) {
Console.Error (error);
}
`
In this example, be sure to replace the Your_transaction_hash_ere with the actual hash you use.
Additional tips
- Update your Solana addiction regularly to make sure you have the latest information on the versions available and all possible problems.
- Consider introducing a repeated mechanism or error processing strategy to avoid the crash of your application if unexpected errors occur.
When performing these steps, you should be able to solve an “invalid signature” error from the Solana Web3 Library. If you still have problems, feel free to ask for further help!
