AttributeError: 'NoneType' object has no attribute 'isoformat'

I got this error when I tried to open the model in the admin panel File "..../venv/lib/python3.8/site-packages/gino_admin/utils.py", line 304, in get_obj_id_from_row result[x] = row[x].isoformat() AttributeError: 'NoneType' object has no attribute 'isoformat'

model

class Notification(db.Model): ...... created_at = db.Column( sa.DateTime, nullable=False, server_default=sa.func.now(), )

read_at = db.Column(sa.DateTime, nullable=True)

The error occurs for the read_at field, since it can be None
