Sorry I didn't set the email alerts for the message board correctly and missed this post. Thanks for reporting this bug.
From the error message, it seems that the problem comes from the function that reads the CSV file and converts it to the SQLite database. To avoid having to read a large CSV file into memory this function reads only a chunk of it. By default, the chunk size is 20,000 lines. It seems that the problem comes from the last chunk where the function tries to skip more lines than there are in the CSV file. This should not happen. Could you share with me the CSV file that you were trying to convert into an SQLite DB?
You can export it from:
