error while using text function with lamdba

i am trying to use this ready code i found it online on github

I installed all the packages:

pip install NRCLex
pip install textblob
python -m textblob.download_corpora

And this is my code:

from nrclex import NRCLex

import numpy as np
import pandas as pd

emotion = NRCLex(text)

df = pd.read_csv('test.csv')

df['emotions'] = df['text'].apply(lambda x: NRCLex(x).affect_frequencies) 

I face this error i this last line:

KeyError  Traceback (most recent call last)

3803 except KeyError as err:

KeyError: 'text'



The above exception was the direct cause of the following exception:
