Error message for index is not specific

[RyanNgWH]

The error message simply states that the index is invalid. It does not specify what makes the index invalid.

The UG only states that "The index must be a positive integer 1, 2, 3, …", based on this, it seems that 9 should be a valid index, however, it is not since there is no person in the application with index 9

Team's Response

Thank you for pointing that out. Indeed, the UG should state that the index must be a both a positive integer and also less than or equal to the number of people listed in the application.

However, this is simply a typo in the UG (the app still correctly reflects that 9 is an invalid index), thus we think this is a very low severity issue.

## :question: Issue severity Team chose [`severity.VeryLow`] Originally [`severity.Low`] - [x] I disagree **Reason for disagreement:** I agree with the team that this would be a documentation bug instead of a feature flaw like I originally reported.  However, based on the the descriptions of a `very low` and `low` bug, I do not believe that this is simply a "purely cosmetic" issue. A purely cosmetic issue would be something like a simple typo, however, I believe that this issue is not a typo but leans more towards missing information from the UG which does in fact affect the user's ability to understand what the error was. I do believe that this issue "appears only in very rare situations and causes a minor inconvenience only" and constitutes for a `low` severity instead of a `very low` severity as the team suggests.
