It might be a good time to take a vacation. If there isn't a lot of pressure for deadlines. Some time off can give you more perspective.

It seems like you are lethargic because the role is easy for you. If you like the place, and you want to develop your career there, then ask your boss, what you could work on to create a bigger impact. You might find that there is more opportunity for you there after all.

If that doesn't interest you, then you can coast for a while. That's fine too. Eventually, you'll probably get bored with this, and then you'll find another job with a more interesting role.
