Add Error Handling to Google Forms

[kimharr24]

Background

Currently, there is no error handling in the AppScript that is executed when a user submits an application through our Google Forms. We should design a strategy to catch any errors that may occur during the submission of a form.

Task

Update the script to catch errors that occur during the submission of a form. The following errors may occur during a form submission:

1. The user is not submitting the form with a husky.neu.edu or northeastern.edu email.
2. The user has not already signed up to our recruitment portal (if this case occurs, then our backend will not be able to associate the user's application with their account in our database, discarding the application).
3. The user has already submitted an application for the current cycle.

The ideal solution will save the state of an application even after submitting an application that triggers one of the aforementioned errors. This makes it so that if a user accidentally submits their application with the wrong email, they don't have to rewrite their answers.
