KeyError: 'content' in Claude_Author.ipynb

I'm using the newest version (https://github.com/mshumer/gpt-author/blob/main/Claude_Author.ipynb)

Added my API keys, ran the cell, filled out writing style, content, and number of chapters. After the 10 chapters have been generated, it always results in this error
