Receiving Key Error = 0 while calculating the polarity in Python

I have two columns - text and title for news articles.

Data looks fine, apologize for a printscreen, just to show the structure.

But it gives me a weird error when I try to calculate the polarity.

# Create  polarity = []    # Creare for loop for Text column only  for i in range(len(jordan_df['text'])):      polarity.append(TextBlob(jordan_df['text'][i]).sentiment.polarity)    # Put data together      polarity_data = {'article_text':jordan_df['text'], 'article_polarity': polarity}  

The weird thing that this code works, when I change jordan_df to some_df with the same structure.

Error:
