Error when the .pgn file ends with a checkmate

[karate]

If I provide a .pgn file that ends with a checkmate, the application breaks when trying to evaluate the last position.

Traceback (most recent call last):

Contents of infos:

Example .pgn file:

[White "Mr. White"]
[Black "Mr. Black"]
[Result "1-0"]
