`KeyError: last-modified` in `kaggle_api_extended.py`

[prabhanjan-jadhav]

This line of code (1829-1830): remote_date = datetime.strptime(response.headers['Last-Modified'], '%a, %d %b %Y %H:%M:%S %Z') in kaggle/api/kaggle_api_extended.py tries to access non-existent key "last-modified" from responses.headers.

kaggle version: 1.5.16

What is the API command I can use to reproduce this problem?

[malharpandya]

I can confirm that the issue still persists, and modifying the function locally with the change in the PR fixes the issue.

Sample script to reproduce the error:

import os
from kaggle.api.kaggle_api_extended import KaggleApi

# set up environment variables (now we don't need kaggle.json)
os.environ["KAGGLE_USERNAME"] = "username" # replace with account username
os.environ["KAGGLE_KEY"] = "key" # replace with generated token

# Initialize and authenticate
api = KaggleApi()
api.authenticate()
