Find on empty string or None raise error

[ttv20]

When I try to compare field to empty string or None it is failing instead of returning empty array

class Image(AppJsonModel):
    name: str = Field(index=True)

# Migrator().run()

Image.find(Image.name == None).all() # TypeError: argument of type 'NoneType' is not iterable
Image.find(Image.name == '').all()   # redis.exceptions.ResponseError: Syntax error at offset 5 near pk
