How can I solve this? as far as I have seen, it has the typ connection.. export async function createMint( wallet: WalletAdapter, mintAuthority: Keypair, decimals: number ) { if (!wallet.connected) { throw new Error('Wallet is not connected'); } const mint = Keypair.generate(); const instructions: TransactionInstruction[] = []; instructions.push( TokenInstructions.initializeMint({ mint: mint.publicKey, decimals: decimals, mintAuthority: mintAuthority.publicKey, }) ); if (!mintAuthority.secretKey || mintAuthority.secretKey.length === 0) { throw new Error('mintAuthority does not contain a private key'); } const connection = new Connection('https://devnet.helius-rpc.com/?api-key=5d69c879-36f4-4acf-87b4-e44a64c07acc'); const transaction = new Transaction().add(...instructions); transaction.feePayer = wallet.publicKey; transaction.recentBlockhash = (await connection.getLatestBlockhash()).blockhash; // Sign the transaction with the payer transaction.sign(mintAuthority); // Serialize and send the transaction try{ const signature = await connection.sendAndConfirmTransaction(transaction,[mintAuthority]); // sendAndConfirmTransaction does not exist for typ connection return { mint, transaction: signature, }; } catch (error) { console.error('Transaction error', error); throw error; } } ```

Instead of calling connection.sendAndConfirmTransaction , you can use the sendAndConfirmTransaction function imported from @solana/web3.js .
