Have a question related to custom program development. I've testing this program
pub mod fluxtility { use super::*; pub fn buy_ticket(ctx: Context<Initialize>, lamports: u64) -> Result<()> { buy_ticket::process_instructions(ctx, lamports) }}How can I call this specific function from nodejs side? Have this code but throwing error -
const buyTicketInstructionData = struct([ u8("instruction"), u64("lamports")]);const data = Buffer.alloc(buyTicketInstructionData.span);buyTicketInstructionData.encode({ instruction: "buy_ticket", lamports: BigInt(LAMPORTS_PER_SOL)}, data);const buyTicketInstruction = new TransactionInstruction({ programId, keys: [ { pubkey: ownerWallet.publicKey, isSigner: true, isWritable: false }, { pubkey: discordWallet.publicKey, isSigner: false, isWritable: false }, { pubkey: SystemProgram.programId, isSigner: false, isWritable: false } ], data: data});const transaction = new Transaction().add(buyTicketInstruction);const tx = await sendAndConfirmTransaction(connection, transaction, [ ownerWallet ]);console.log(tx);And the error is -
