Anki CSV Importer not working - KeyError: 'Front'

I am trying to use the Anki CSV Importer to import a CSV file I have into an Anki deck.

My CSV file has 2 columns (Answer, Question) and, as of right now, 2628 rows (whose number will grow with time), looking like this:

Answer, Questiontranslation1,word1translation2,word2[etc]

I have added the AnkiConnect add-on to Anki, as recommended by the author of the code on Github (I am running it on Windows 11).

I am also making sure an instance of Anki is running before I execute the Anki CSV importer.

My program crashes, here is the exception I am getting:

I don't understand why the field "Front" should be available on the variable "n", I have checked the code and don't understand what this should be referring to and why it is not getting generated when I execute it.

Also, my deck in Anki is currently empty, so I am not sure why it is stating "0 new notes and updating 2627 existing notes".

I have tried debugging the code by providing the args as manual input, however, I don't understand the issue.
