Currently find issue when find PDAs for this code, basically i am using the the 1. static string "version" 2. publickey of PDA of case 3. the latest_version_id of case as elements of seeds to generate. but i find my anchor program and test file can't generate same PDAs
Anchor Code:
#[derive(Accounts)]#[instruction(case_id: u32)]pub struct CreateVersion<'info> { #[account( mut, seeds = [CASE_SEED.as_bytes(), &case_id.to_le_bytes()], bump, )] pub case: Account<'info, Case>, #[account( init, payer = authority, space = 8 + U32_SIZE + 4 + 4 + 4 + MAX_TOKEN_NAME_LEN + 4 + MAX_TOKEN_TICKER_LEN + 4 + MAX_TOKEN_IMAGE_LEN + U64_SIZE + 4 + PUBKEY_SIZE + U32_SIZE, seeds = [ b"version", case.key().as_ref(), &((case.latest_version_id + 1).to_le_bytes()) ], bump, )] pub version: Account<'info, Version>, #[account(mut)] pub authority: Signer<'info>, pub system_program: Program<'info, System>,}using this account here:
pub fn create_version( ctx: Context<CreateVersion>, token_name: String, token_ticker: String, token_image: String, token_total_supply: u64, token_address: Pubkey, case_id: u32, ) -> Result<()> { let case_account = &mut ctx.accounts.case; let version_account = &mut ctx.accounts.version; msg!("Current latest_version_id: {}", case_account.latest_version_id); // Use the current version ID for seed generation let current_version_id = case_account.latest_version_id; // Initialize the version account with the current version ID version_account.id = current_version_id + 1; // This version is (latest_version_id + 1) version_account.token_name = token_name; version_account.token_ticker = token_ticker; version_account.token_image = token_image; version_account.token_total_supply = token_total_supply; version_account.token_address = token_address; version_account.case_id = case_account.id; version_account.authority = *ctx.accounts.authority.key; // Increment case's version ID after the version account is created case_account.latest_version_id += 1; Ok(()) }ts test code:
it("Creates a new version for the case", async () => { // Fetch the case account first to get the latest_version_id const caseAccount = await program.account.case.fetch(casePDA); const latestVersionId = caseAccount.latestVersionId; // Fetch the current latest_version_id // Increment the latest_version_id by 1, as per your seed logic const nextVersionId = latestVersionId + 1; const caseIdBytes = Buffer.alloc(4); // 4-byte buffer for storing u32 caseIdBytes.writeUInt32LE(nextVersionId); // Get PDA for the version account using the same seeds as in your program const [versionPda, _] = await anchor.web3.PublicKey.findProgramAddressSync( [ Buffer.from("version"), casePDA.toBuffer(), caseIdBytes, // This represents latest_version_id + 1 ], program.programId ); versionPDA = versionPda; const tx = await program.methods .createVersion("SampleToken","STK","https://example.com/sample-token-image.jpg", new anchor.BN(1000000), // Token supply anchor.web3.PublicKey.default, // Sample token address caseId // Pass the correct case ID here ) .accounts({ case: casePDA, version: versionPDA, authority: provider.wallet.publicKey, systemProgram: anchor.web3.SystemProgram.programId, }) .rpc(); console.log("Version created, transaction signature:", tx); });if i run this test script for this smart contract, i will keep getting this error (have tried many times of solana playground as well, getting the same result):
