Question

I'm getting this error in selling in auctioneer sdk

'Program neer8g6yJq2mQM6KbnViEDAD4gr3gRZyMMf4F2p3MEh invoke [1]',
    'Program log: Instruction: Sell',
    'Program 11111111111111111111111111111111 invoke [2]',
    'Program 11111111111111111111111111111111 success',
    'Program log: AnchorError caused by account: seller_trade_state. Error Code: ConstraintSeeds. Error Number: 2006. Error Message: A seeds constraint was violated.',

    'Program neer8g6yJq2mQM6KbnViEDAD4gr3gRZyMMf4F2p3MEh failed: custom program error: 0x7d6'

i'm finding seller trade sate like this

 const sellerTradeState = await  anchor.web3.PublicKey.findProgramAddress(
    [
      Buffer.from('auction_house'),
      publicKey.toBuffer(),
      aH.toBuffer(),
      associatedAddress.toBuffer(),
      WRAPPED_SOL_MINT.toBuffer(),
      mint.toBuffer(),
      new BN (10000000).toBuffer('le',8),
      new BN (Math.ceil(1)).toBuffer('le',8),
      
    ],
    AUCTION_HOUSE_PROGRAM_ID,
  );

I tried many arguments like u64::MAX's value and regular buyer price, but every time pda is wrong. what should i change?

Answer 1

i solved it by using this as trade state.

async function getAuctionHouseTradeState( 
    auctionHouse, 
    wallet, 
    tokenAccount, 
    treasuryMint, 
    tokenMint, 
    tokenSize, 
    buyPrice 
  ) { 
    return await PublicKey.findProgramAddress( 
      [ 
        Buffer.from('auction_house'), 
        wallet.toBuffer(), 
        auctionHouse.toBuffer(), 
        tokenAccount.toBuffer(), 
        treasuryMint.toBuffer(), 
        tokenMint.toBuffer(), 
        new BN(buyPrice).toArrayLike(Buffer, "le", 8), 
        new BN(tokenSize).toArrayLike(Buffer, "le", 8), 
      ], 
      AUCTION_HOUSE_PROGRAM_ID 
    ); 
  }

  const [sellerTradeState, tradeBump] = await getAuctionHouseTradeState( 
    aH, 
    publicKey, 
    associatedAddress, 
    WRAPPED_SOL_MINT, 
    mint, 
    1, 
    "18446744073709551615" 
  );
