duplicate key error index in mongoengine

I have a Page model as follow and the page_id field isn't unique but I can't create an instance from Page and this error rises
OperationError: Could not save document (insertDocument :: caused by ::11000 E11000 duplicate key error index: shopify.page.$pageId_1 dup key: { : null }) I have no idea that why the duplicate key error rises when the page_id field isn't unique

The Site model : 

class Page(Document):

    # page identity
    page_id = StringField()
    store = ReferenceField('Store')
    is_product = BooleanField(default = False)
    is_homepage = BooleanField(default = False)
    product = ReferenceField('Product')
    requests = ListField(EmbeddedDocumentField('Request'))

    # page stat
    visitors = IntField(default = 0)
    views = IntField(default = 0)
    past_days = ListField(EmbeddedDocumentField('DayStat'))

Yes,I also removed the unique=True from the field attribute, and after that dropped the Collection and ran the code again. This resolved the issue.

it's just because of some old Document in database that in past have different fields and when the new changes applied because of different objects type in Collection when a function running it unable to recognize the type of object of field and go down !
one solution is dropping the Collection and if your Collection is too important you can write a script that delete old objects and make a new instance from them.
