The issue occurs when attempting to save details in the portal view without selecting a country. At this point [1], a string "False" is passed as the 'country_id', and the system attempts to convert it into an integer using typecasting (int()).

To resolve this issue, the condition is added to ensure that only integer values are passed as a 'country_id'.
