How do I pass an array to a MongoRepository #Query? - mongodb

Question

Using Spring Data MongoDB. And I have defined this query on my MongoRepository:
#Query("{'type':?0, 'tags.type':?1, 'tags.softSkill.name': {$all: ?2}}")
List<Foo> findByTypeAndTags_TypeAndTags_SoftSkills(
FooType type, TagType tagType, String[] softSkills);
As I want to use $all operator I can't build the query through the method-naming way so I use the #Query annotation.
The issue is that it doesn't like the String[] that I try to pass for ?2 argument. I've tried with a List but the the error remains.
value expected to be of type java.util.List but is class java.lang.String toString:fooStr
On a mongo-shell would be like: $all: ['foo1','foo2']
Foo abstract entity is like:
#Data
#Document(collection="foes")
public abstract class Foo {
/*...*/
protected List<Tag> tags = new ArrayList<>();
}
Tag asbtract pojo:
#Data
public abstract class Tag {
protected final TagType type;
protected TagLevel level;
}
TagSoftSkill pojo:
#Data
#EqualsAndHashCode(callSuper=true)
public class TagSoftSkill extends Tag{
private SoftSkill softSkill; //another pojo that has a "name" field
public TagSoftSkill() {
super(TagType.SOFT_SKILL);
}
}
I already debugged and softSkills prints [foo]. I modified the value to be like ['foo'] but there are no changes.

I didn't mention that I'm using fongo. Switched to real mongo and everything works as it should. So it's a fongo issue.
