I am getting an error message when creating a signature
Error:
TransactionExpiredBlockheightExceededError: Signature 2XqzFuyv5YWpDPTT87CVu48QJPemGSu5rbCazrNBgY6D3mS8rugKugtzXDGpN6XZF8FPyWwXQvzfm4ZyMx6gTf6j has expired: block height exceeded.
Signature created like this:
const transaction = transaction.add(...)
transaction.feePayer = publicKey;
transaction.recentBlockhash = (await connection.getLatestBlockhash()).blockhash;
const latestBlockHash = await connection.getLatestBlockhash()
// ----> Phantom recommended way of signing tx
const { signature } = await provider.signAndSendTransaction(transaction);
const confirmation = await connection.confirmTransaction(
{
blockhash: latestBlockHash.blockhash,
lastValidBlockHeight: latestBlockHash.lastValidBlockHeight,
signature,
}
);
After few seconds/minute or 2 I get the above error message although the TX is confirmed and finalized.
How to handle this? Why is the error popping up if the tx gets added to the block?
connection.confirmTransaction, not from creating the signature.connection.confirmTransaction(signature)you would not get this error, though this approach is apparently deprecated now.
