When the type of feature_id is float there throw an error:
"ValueError: invalid literal for int() with base 10:"
Because you get a ValueError if you pass a string representation of a float into int, or a string representation of anything but an integer (including empty string). If you do want to pass a string representation of a float to an int, as it points out above, you can convert to a float first, then to an integer.
