'NoneType' object has no attribute 'type' when using Konch and Pandas?

[Peder2911]

I am encountering a breaking bug that causes Konch to crash. I am using Konch inside a venv using pipx, with Pandas, doing some data analysis. Random commands raise the following exception (last command was dataframe["col"].values):

~/.local/pipx/venvs/konch/lib/python3.8/site-packages/ptpython/completer.py in get_completions(self, document, complete_event)
    258             else:
    259                 # Move function parameters to the top.
--> 260                 jedi_completions = sorted(
    261                     jedi_completions,
    262                     key=lambda jc: (

~/.local/pipx/venvs/konch/lib/python3.8/site-packages/ptpython/completer.py in <lambda>(jc)
    262                     key=lambda jc: (
    263                         # Params first.
--> 264                         jc.type != "param",
    265                         # Private at the end.
    266                         jc.name.startswith("_"),

~/.local/pipx/venvs/konch/lib/python3.8/site-packages/jedi/api/classes.py in type(self)
    717             )
    718

    720
    721     def get_completion_prefix_length(self):

    187             for value in self._name.infer():
    188                 return value.api_type

     79             definition = self.tree_name.get_definition()

     81                 if function_is_property(definition):

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

Heres' a reprex:

import pandas as pd
import numpy as np
data = pd.DataFrame(np.zeros((10,10)),columns=list(string.ascii_letters[:10]))
data["a"].values

This raises the above error.
