Incorrect error message for invalid dates

[Sheemo]

When executing the command add_task n/My Invalid Birthday d/32/03/2023, the error message simply says Task deadline should only contain numeric values in the format "DD/MM/YYYY" and it should not be blank.

However, my input conforms to the format, just that my date is invalid. The error message should be more detailed in saying that the date is invalid.

Team's Response

This is a duplicate of #303. The current error message simply grouped invalid dates under dates with the wrong format, which can be too general. We agree that the error message could have been more specific. However, we think that it is a feature flaw that involves the specificity of error messages instead of a functionality bug.

The 'Original' Bug

[The team marked this bug as a duplicate of the following bug]

Error message for date format is not specific

Steps to reproduce:

1. add_task n/Buy cookie cutter d/20/13/2023

2. add_task n/Buy cookie cutter d/30/2/2023

The two errors above are different, the first is format error while second is input invalid error, but they are not addressed or differentiated.

Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

We agree that we could have differentiated the error message for different errors. The error message simply categorized invalid dates as dates with the wrong format, which makes it too ambiguous.
