How to combine two jupiter swaps in one?

Question

I'm new to solana and I'm trying to combine two swap transactions I got from jupiter API. In my attempt I got multiple types of errors depending on how the transaction's structure. I will post an error logs example but sometimes its different

logs: [ 'Program ComputeBudget111111111111111111111111111111 invoke [1]', 'Program ComputeBudget111111111111111111111111111111 success', 'Program ComputeBudget111111111111111111111111111111 invoke [1]', 'Program ComputeBudget111111111111111111111111111111 success', 'Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL invoke [1]', 'Program log: CreateIdempotent', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]', 'Program log: Instruction: GetAccountDataSize', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 1569 of 1394295 compute units', 'Program return: TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA pQAAAAAAAAA=', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success', 'Program 11111111111111111111111111111111 invoke [2]', 'Program 11111111111111111111111111111111 success', 'Program log: Initialize the associated token account', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]', 'Program log: Instruction: InitializeImmutableOwner', 'Program log: Please upgrade to SPL Token 2022 for immutable owner support', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 1405 of 1387708 compute units', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]', 'Program log: Instruction: InitializeAccount3', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 3158 of 1383826 compute units', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success', 'Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL consumed 19315 of 1399700 compute units', 'Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL success', 'Program JUP6LkbZbjS1jKKwapdHNy74zcZ3tLUZoi5QNyVTaV4 invoke [1]', 'Program log: Instruction: SharedAccountsRoute', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]', 'Program log: Instruction: TransferChecked', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 6200 of 1363832 compute units', 'Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA success', 'Program log: AnchorError caused by account: swap_program.
