@Document(collation="company")

This looks like a typo and the cause of your issue. You try to set collection name, but instead of collection you use collation property: https://docs.mongodb.com/manual/reference/collation/

The correct form of annotation would be:

@Document(collection = "company")
public class Company {
    // ...
}

Or simpler – since value is an alias for collection:

@Document("company")
public class Company {
    // ...
}

You can even completely omit collection name. In that case Spring will use class name as collection name:

@Document // name of collection wil be "company", as per class name
public class Company {
    // ...
}

The last example is why this was working for you with e.g. count queries, even though you did not provide collection name explicitly.
