I have been using a PRAW Reddit script application instance to get comments and submissions from the movies and science subreddits. I supply my username and password too. I am able to to get them properly from the movies subreddit but not from the science subreddit. The following exception is generated in the science subreddit: prawcore.exceptions.Forbidden: received 403 HTTP response . However, this only happens for the science subreddit and not movies. My PRAW version is 7.7.0. I tried searching on the internet and tried changing my user agent, but that didn't help.

​

I checked this file: https://github.com/praw-dev/prawcore/blob/main/prawcore/exceptions.py which states that the Forbidden exception occurs when "authentication is not permitted for the request" but I don't understand how that can happen for science but not movies. Would really appreciate any help. Thanks! Traceback:
