AttributeError: 'LuxDataFrame' object has no attribute '_type_override'

[MaryDonovanMartello]

I am trying to specify an intent (df.intent = ['PERS_WGT_NUM']). I have been successful with other datasets. However, with my current dataset I am getting the following error:

AttributeError: 'LuxDataFrame' object has no attribute '_type_override'

Any help would be appreciated. Thank you.
