I am very grateful for your knowledge to be shared. Through the knowledge you share I learn many new and very interesting things. while practicing project-8-token-lottery. I get an error when running Anchor test. It is the error: "Program log: AnchorError occurred. Error Code: InvalidSecpSignature. Error Number: 6016. Error Message: InvalidSecpSignature". I have tried many ways but have not fixed it. Please give me advice. Thank you so much! my code in Anchor test it("Is committing and revealing a winner",async()=>{ const queue = new anchor.web3.PublicKey("FfD96yeXs4cxZshoPPSKhSPgVQxLAJUT3gefgh84m1Di"); //devnet const queueAccount = new sb.Queue(switchboardProgram, queue); const rngKp = anchor.web3.Keypair.generate(); try { await queueAccount.loadData(); } catch (err) { console.log("Queue account not found"); process.exit(1); } const [randomness, ix] = await sb.Randomness.create(switchboardProgram, rngKp, queue); console.log("Created randomness account.."); console.log("Randomness account", randomness.pubkey.toBase58()); console.log("rkp account", rngKp.publicKey.toBase58()); const createRandomnessTx = await sb.asV0Tx({ connection:provider. connection, ixs: [ix], payer: wallet.publicKey, signers: [wallet.payer,rngKp], computeUnitPrice: 75_000, computeUnitLimitMultiple: 1.3, }); const blockhashContext = await provider.connection.getLatestBlockhashAndContext(); const createRandomnessSignature = await provider.connection.sendTransaction(createRandomnessTx); await provider.connection.confirmTransaction({ //sign the transaction signature: createRandomnessSignature, blockhash: blockhashContext.value.blockhash, lastValidBlockHeight: blockhashContext.value.lastValidBlockHeight }); console.log( "Transaction Signature for randomness account creation: ", createRandomnessSignature ); const sbCommitIx = await randomness.commitIx(queue); // commint a winer on chain. const commitIx = await program.methods.commitAWinner() .accounts( { randomnessAccountData: randomness.pubkey } ) .instruction(); const commitTx = await sb.asV0Tx({ connection: switchboardProgram.provider.connection, ixs: [sbCommitIx, commitIx], payer: wallet.publicKey, signers: [wallet.payer], computeUnitPrice: 75_000, computeUnitLimitMultiple: 1.3, }); const commitSignature = await provider.connection.sendTransaction(commitTx); await provider.connection.confirmTransaction({ signature: commitSignature, blockhash: blockhashContext.value.blockhash, lastValidBlockHeight: blockhashContext.value.lastValidBlockHeight }); console.log( "Transaction Signature for commit: ", commitSignature ); // choose a winer const sbRevealIx = await randomness.revealIx(); const revealIx = await program.methods.choseWiner() .accounts({ randomnessAccountData: randomness.pubkey }) .instruction(); const revealTx = await sb.asV0Tx({ connection: switchboardProgram.provider.connection, ixs: [sbRevealIx,revealIx], payer: wallet.publicKey, signers: [wallet.payer], computeUnitPrice: 75_000, computeUnitLimitMultiple: 1.3, }); const revealSignature = await provider.connection.sendTransaction(revealTx); await provider.connection.confirmTransaction({ signature: revealSignature, blockhash: blockhashContext.value.blockhash, lastValidBlockHeight: blockhashContext.value.lastValidBlockHeight }); // await provider.connection.confirmTransaction(revealSignature,"confirmed"); console.log("Transaction Signature revealTx: ", revealSignature); });
