no error message thrown when adding some invalid date

[nus-se-script]

no error message thrown when input date is 30-02-2023, which does not exist, into add-inflow command. user may type too fast and type 30-02-2023 instead of 03-02-2023. However the transaction that is added is 28-02-2023 (see under second view-history command in picture), which may be the wrong date the user intends to input and would not know they have input a wrong date, would be good to flag to user so they will not accidentally add a wrong date.
expected error message: invalid date
actual output: inflow is added successfully (see first command in picture)

After the first command, the app showed "Please enter a valid date or time", which means the inflow was not added. Are you sure that the transaction was added from the command shown in the screenshot?
