You will hear about errors from your users
In plain English: Nothing tells you when your app breaks for a user. Without error tracking, you only find out when someone is annoyed enough to email you, if they ever do.
What happens if you ship it
Your app fails for a week before someone is annoyed enough to email you.
How to fix it technical
Add an error tracker such as Sentry on both the client and the server.

Questions
What is error tracking?
A service that records errors from your app as they happen, with details, and alerts you. Sentry is a common example.
Do I need it before launch?
It is not a blocker, but it is the cheapest way to see what breaks in the first week with real users.
