InstructionFallbackNotFound. Nomor Error: 101. Pesan Error: Fungsi fallback tidak didukung

Anda harus memberikan instruction discriminator ke data transaksi Anda seperti yang telah disebutkan oleh Ademola. Yang dapat Anda lakukan adalah mengambil instruction discriminator lalu menambahkannya ke data Anda pada 8 byte pertama. Ambil Instruction Discriminator di Rust pub fn sighash(namespace: &str, name: &str) -> [u8; 8] { let preimage = format!("{}:{}", namespace, name);

let mut sighash = [0u8; 8]; sighash.copy_from_slice( &anchor_client::anchor_lang::solana_program::hash::hash(preimage.as_bytes()).to_bytes() [..8], ); sighash }

println!("{:?}", sighash("global", "initialize"));

Ambil Discriminator Instruction di typescript function sighash(nameSpace: string, ixName: string): Buffer { let name = snakeCase(ixName); let preimage = ${nameSpace}:${name}; return Buffer.from(sha256.digest(preimage)).slice(0, 8); }

namespace harus global Berikut adalah contoh di Typescript // Craft the InstructionBuffer const ixBuffer = sighash('global','initialize');

const instructionBuffer = Buffer.concat([ ixBuffer, // namespace+method_name OtherBuffer, // Other Data that you want to pass to the instruction. ])

// Craft the Instruction const transactionInstruction = new TransactionInstruction({ programId: programAddress, data: instructionBuffer, keys : [ ... ] })
