Problem with EmbeddedFiled (Can't query via graphql

Hi Guys, Currently I set up a simple model, schema, type as below. However, I don't know why when I use EmbeddedField it works in the runtime (It doesn't show any runtime error) but I can't operate any query on this field.

`Error messge`
"Cannot query field \"metadata\" on type \"Scenario\"

Environment:
Python3.6
Python3.8

Computer system
Mac: MacOC

Models.py
```
# EmbeddedDocument Models
class Scenario(EmbeddedDocument):
name = models.StringField(max_length=100)
creationDatetime = models.DateTimeField()
lastUpdateDatetime = models.DateTimeField()
data = models.DictField()
cancellation = models.BooleanField(default=False)
isDefault = models.BooleanField(default=False)

# Document Models
class View(Document):
name = models.StringField(max_length=100)
scenarios = models.EmbeddedDocumentListField(Scenario)
cancellation = models.BooleanField(default=False)
```

Types.py
```
class ViewType(MongoengineObjectType):
class Meta:
model = View
interfaces = (relay.Node,)
```

Schema.py
```
class Query(graphene.ObjectType):
node = Node.Field()
view = MongoengineConnectionField(ViewType)
views = graphene.List(ViewType)

def resolve_views(self, info, name):
return View.objects.get(name=name)
```

Also, I have tried the solution on this issue as well
https://github.com/graphql-python/graphene-mongo/issues/32

I will get an error when I declare the reference model

Start by reviewing the EmbeddedDocument definitions in Models.py and how ViewType in Types.py exposes View through the Query fields in Schema.py. Reproduce the reported inability to query metadata or the embedded scenarios field and determine which schema behavior should be corrected so the embedded data is queryable without runtime errors.
