How to solve Query failed with error code 13 and error message 'command find requires authentication'

Question

I'm getting this error when making requests to my spring boot api hosted on a Vultr VPS. I enabled authentication in the mongod.conf file. Afterward, I added a user to the admin database called dbOwner with the dbOwner role. I can connect to the database via Robo3t, but my spring boot api is having trouble doing the same.

My application.properties is as such. Would prefer to use mongodb uri, but haven't gotten that far yet.

spring.data.mongodb.authentication-database=admin
spring.data.mongodb.database=my_db
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.user=dbOwner
spring.data.mongodb.password=secret
server.port=80

The full stack trace is

I'm utterly and completely confused because I've never changed the authentication settings in the mongod.conf before therefore other projects I've worked on haven't actually required authentication to connect. I'm adding the authentication in response to a hack that occurred on my empty database since it had no auth. Any help would be greatly appreciated.
