I am writing a Solana Program using Anchor framework.
I can't seem to get rid of a signing error I'm having while testing.
Instruction Accounts validation:
#[derive(Accounts)]pub struct InitializeAuction2<'info> {/// State of our auction program (up to you)#[account(init,payer = signer,space = 8 + BoyncAuction::AUCTION_SIZE, )]pub state: Account<'info, BoyncAuction>,#[account(mut)]pub signer: Signer<'info>,system_program: Program<'info, System>,rent: Sysvar<'info, Rent>,}Instruction Handler:}
pub fn initialize2(ctx: Context<InitializeAuction2>, app_idx: i64, amount: u64) -> Result<()> {msg!("[BoyncProgram] Initializing new Boync Auction State");let auction_state = &mut ctx.accounts.state;auction_state.end_auction_at = app_idx; // App index is UnixTimestampauction_state.authority = ctx.accounts.signer.key().clone();auction_state.state = AuctionState::create();Ok(())}Test:
const mint = /* previously created mint account */const user1 = new anchor.web3.Keypair();const uid = new anchor.BN(parseInt((Date.now() / 1000).toString()));const uidBuffer = uid.toBuffer("le", 8);let [auctionStatePubKey, auctionStateBump] =await anchor.web3.PublicKey.findProgramAddress([Buffer.from("auction"),user1.toBuffer(),mint.toBuffer(),uidBuffer,],program.programId);const tx1 = await program.methods.initialize2(uid, amount).accounts({state: auctionStatePubKey,signer: user1.publicKey,systemProgram: anchor.web3.SystemProgram.programId,rent: anchor.web3.SYSVAR_RENT_PUBKEY,}).signers([user1]).rpc();...I hope I did not miss anything. Please let me know if context is not enough.Anyway, I can't submit this program call transaction. It fails with:
Error: Signature verification failedat Transaction.serialize (node_modules/@project-serum/anchor/node_modules/@solana/web3.js/src/transaction.ts:586:13)at Provider.send (node_modules/@project-serum/anchor/src/provider.ts:116:22)at processTicksAndRejections (node:internal/process/task_queues:96:5)at MethodsBuilder.rpc [as _rpcFn] (node_modules/@project-serum/anchor/src/program/namespace/rpc.ts:25:23)I tried making signer: provider.wallet.publickey, no go.
Any help as well as why this happens is greatly appreciated.

This is a shot in the dark, but since you're not specifying state as a PDA, Anchor is probably expecting a signature from that account too. Try changing up your instruction definition to:
#[derive(Accounts)]pub struct InitializeAuction2<'info> {/// State of our auction program (up to you)#[account(init,payer = signer,space = 8 + BoyncAuction::AUCTION_SIZE,seeds = [b"auction", signer.key().as_ref(), mint.key().as_ref(), 8u64.to_le_bytes()], bump)]pub state: Account<'info, BoyncAuction>,#[account(mut)]pub signer: Signer<'info>,system_program: Program<'info, System>,rent: Sysvar<'info, Rent>,}You'll probably also need to pass in the mint and bump seed data.
