I am new to Spring Boot, following tutorials to create a simple restAPI using MongoDB, and I keep encountering this same error " Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations'
My db is hosted on atlas.

From here I expected to be able to launch my VM and start sending a post request to my api, but instead I am getting this error on startup (only posted a line because block was marked as spam)
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'itemController': Unsatisfied dependency expressed through field 'itemService': Error creating bean with name 'itemServiceImpl': Unsatisfied dependency expressed through field 'itemRepository': Error creating bean with name 'itemRepository' defined in com.github.nohgo.grocerylist.repository.ItemRepository defined in @EnableMongoRepositories declared on MongoRepositoriesRegistrar.EnableMongoRepositoriesConfiguration: Cannot resolve reference to bean 'mongoTemplate' while setting bean property 'mongoOperations'
I know this error is likely just me making some stupid mistake but I am unable to see where I deviate from these tutorials. Any help is appreciated.
Edit:
GroceryListApplication
package com.github.nohgo.grocerylist;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class GroceryListApplication { public static void main(String[] args) { SpringApplication.run(GroceryListApplication.class, args); }}
