ошибка разбора: ожидаемый разделитель между значениями

Question

Файл My PrivateIP-List.txt содержит данные ниже

axx, XXXXXXXXXXX, 
bxx, XXXXXXXXXXXX, 
cxx, XXXXXXXXXXXX,

Когда я запускаю приведенный ниже скрипт в цикле, скрипт работает нормально, но выдает ошибку разбора во время работы и продолжает.

Ошибка:

parse error: Expected separator between values at line 1, column 78 
parse error: Expected separator between values at line 1, column 78 
parse error: Expected separator between values at line 1, column 78

Во время выполнения скрипта
