Nested ModelSerializer won't validate: Expected a dictionary

[rvanlaar]

A non model serializer with a nested model serializer doesn't validate. It expects a dictionary.
Below is a minimal example.

The end goal is to show all answers with a little bit of meta data.
Is there another or better way to wrap a model serializer in a JSON object?
I would like to use a serializer so that drf spectacular will show it as documentation.

class AnswerSerializer(serializers.ModelSerializer):
    textniveau = serializers.CharField(source="niveau")
    class Meta:
        model = Answer
        fields = ["textniveau"]

class AnswerOverview(serializers.Serializer):
    question = serializers.CharField()
    answers = AnswerSerializer(many=True)
    
answers = Answers.objects.all()
question = "What is Django?"

aos = AnswerOverviewSerializer(data={"question"=question, answers=answers})
aos.is_valid()
# False
aos.errors
# {'answers': ['{'non_field_errors': [ErrorDetail(string='Invalid data. Expected a dictionary, but got Anwers.', code='invalid')]}, ...

The solution is to enter the data without the data= part.

@rvanlaar how did that work?
