Spatial DataFrame to_featureclass() strips attribute data

[A_Schwab]

I have a spatially-enabled dataframe with 16 columns: 

sedf.columns
Index(['issuedDate', 'weatherType', 'warningLikelihood', 'warningLevel',
'warningStatus', 'warningHeadline', 'whatToExpect', 'warningId',
'warningVersion', 'warningFurtherDetails', 'modifiedDate',
'validFromDate', 'affectedAreas', 'warningImpact', 'validToDate',
'SHAPE'],
dtype='object')

sample: 

>>> sedf.iloc[0]
issuedDate                                            2023-12-05T10:15:10Z

Name: 0, dtype: object

 when I run sedf.to_featureclass("path/to/gdb/featureclass"), the resulting featureclass only has 4 of these columnd: SHAPE, modifiedDate, validFromDate, validToDate. 

Exporting the same data from geopandas to geojson or GPKG works fine. 

I've tried using sanitize_columns=False on the SEDF but it makes no difference. 

Does anyone know what might be causing the loss of this attribute data and how I can keep it when saving to featureclass/GDB?

In the past, I remember to_featureclass failing if you had any Python lists in your dataframe. I'm not sure if this is a problem in your case (only noting it because I see lists in the screen).

That was it, thank you! 

I converted the lists to strings and now it works as expected.
