I saw simillar question here here

but it is not work on me.

            instructions_swap = make_swap_instruction(amount_in,

                                                      pool_keys,

            closeAcc = (close_account(params))
            if swap_token_account_Instructions != None:
                swap_tx.add(swap_token_account_Instructions)

What can I do for fix it?
