Error: Failed to get recent blockhash

[jude98]

I’ve integrated Solana Pay into my application, and it has been working smoothly until recently. However, I’ve started encountering the following error:

Error: failed to get recent blockhash: SolanaJSONRPCError: failed to get recent blockhash: Method not found
    at Connection.getRecentBlockhash

This issue arises when calling the createTransfer method:

const transaction = await createTransfer(
 connection,
 provider.publicKey,
 {
   recipient,
   amount,
   splToken,
   reference,
 },
 { commitment: "confirmed" }
);

Environment

• Network: Devnet
• RPC Provider: Helius RPC
• Commitment Level: confirmed
• Library: Solana Pay ("@solana/pay": "^0.2.5")

It appears that getRecentBlockhash has been deprecated, and this method is still being used internally when creating a transfer transaction. This may be leading to compatibility issues, particularly with newer RPC providers like Helius.
