I'm totally new to solana so I'm following the 2023 bootcamp. Episode 1 has a repo you follow with the devrel, which starts with quest 1. He runs it fine in the video but I've encountered several problems. I am a newb mostly so I'm not exactly sure what's going on. First is the warning I would keep getting from getMinimumBalanceForRentExemption. I tried hard coded values similar to what I saw in the video but the error after still gets thrown. The actual error is:
throw new SendTransactionError({ ^SendTransactionError: Simulation failed. Message: Invalid params: unknown variant `single`, expected one of `processed`, `confirmed`, `finalized`.. Catch the `SendTransactionError` and call `getLogs()` on it for full details.I can't find anything specific to this error, does anyone have any context? I think every quest in the episode uses the account that this TX is supposed to create so I can't continue working along the video
Here is the code from the file I'm trying to run:
// generate a new, random address to create on chain const keypair = Keypair.generate(); console.log("New keypair generated:", keypair.publicKey.toBase58()); // on-chain space to allocated (in number of bytes) const space = 0; const lamports = await connection.getMinimumBalanceForRentExemption(space); console.log("Total lamports:", lamports); // create this simple instruction using web3.js helper function const createAccountIx = SystemProgram.createAccount({ // `fromPubkey` - this account will need to sign the transaction fromPubkey: payer.publicKey, // `newAccountPubkey` - the account address to create on chain newAccountPubkey: keypair.publicKey, // lamports to store in this account lamports, // total space to allocate space, // the owning program for this account programId: SystemProgram.programId, }); // get the latest recent blockhash let recentBlockhash = await connection.getLatestBlockhash().then(res => res.blockhash); // create a message (v0) const message = new TransactionMessage({ payerKey: payer.publicKey, recentBlockhash, instructions: [createAccountIx], }).compileToV0Message(); // create a versioned transaction using the message const tx = new VersionedTransaction(message); tx.sign([payer, keypair]); console.log("tx after signing:", tx); // actually send the transaction try{ const sig = await connection.sendTransaction(tx); console.log("Transaction completed."); console.log(explorerURL({ txSignature: sig })); } catch (error: any) { console.error("Transaction FAILED", error); if (error.logs) { console.error("Transaction logs: ", error.logs) } }
