Description

I've added error handling to the existing functions so that the server doesn't crash if the user sends an incorrect value in their request.

• Deleted unnecessary response output
• Added drawer stage to vocabulary output
• Added description property to vocabulary card

Motivation and Context

These changes are required so that the server does not crash in the event of incorrect requests.
