KeyError from get_inferred_types when validating simple script

[mdickinson]

Description

I'm getting a traceback (ending in the line KeyError: '4305da1ea25c27fce08bd14001b76fd54fe42a0724bbd5168c76680a56eda5be') when running flake8 on a simple test script. It appears to have to do with a bad column number passed to jedi in get_inferred_types.

Here's the test script, saved on my machine as test.py:

value = 35.0
something = str(
    value).replace(' ', ',').split(',')

Steps to Reproduce

To reproduce:

• Save the above script in your current directory under the name test.py
• Create a new Python 3.10 venv and activate it
• Do a pip install flake8-encodings jedi
• Run python -m flake8 test.py

Example session showing the above:

Without Jedi in the mix, the file validates correctly.

Actual result:

See above for the traceback.

Expected result:

Successful validation (no output to the console, zero exit code)

Reproduces how often:

100% reproducible.
