Error with pandas in the Labs Python Integration

Hi all,

I am trying to run a script using the Labs Python Integration node and I encounter an error that does not happen when I execute the code in pure Python.

Code:

# the column last is Local Date in KNIME
dfc[fd_revw] = 3
dfc['expected'] = dfc['last'] + pd.to_timedelta(dfc['estimate'] * 365, unit='D')

I get the following exception:

Executing the Python script failed: Traceback (most recent call last):
File "<string>", line 18, in <module>
File "C:\Users\md45qh\AppData\Local\Programs\Python\Python37\lib\site-packages\pandas\core\ops\common.py", line 69, in new_method

res_values = op(left, right)
TypeError: unsupported operand type(s) for +: 'KnimePandasExensionArray' and 'TimedeltaArray'

Does anyone know what might be going on?
