BadValueError: Expected list or tuple, got None

Question

I'm trying to clear out an ndb.StringProperty(repeated=True) value by setting it to None but am getting the error:

BadValueError: Expected list or tuple, got None

It's pretty straightforward, but the code I'm using is:

g.kids_names = None
g.put()

Answer 1

It is a repeated property. Try setting it to an empty list: []
