Same issue. I added str to my abstract classes and now it is a validation error. Django admin says that my values must be an instance of <class 'list'> to my models. ArrayField and an instance of <class 'dict'> to my models.EmbeddedField

yeah same issue with me, I work with Django 3.8 and Djongo 1.3.3
