TypeError: argument of type 'NoneType' is not iterable

While trying to download images through this
instaloader --filename-pattern={date_utc}_UTC_{profile} --post-filter="'4 letters' in caption" --no-metadata-json --no-compress-json <profile-name>

I got this error

[170/1382] Traceback (most recent call last):

Running Instaloader 4.1.1

This kind of error is not handled? or is it an issue from my end?

--post-filter="'4 letters' in caption" fails with a TypeError exception if caption is None. Better use --post-filter="caption and '4 letters' in caption".

Thank You

You're welcome :)

Anyway I want to keep this issue open since I like your suggestion of catching exceptions that are raised during evaluation of the --post-filter, instead of failing and terminating the whole program.
