Hey all. Just wanted to share a very basic error handling format that restarts a script after a delay if there is a Reddit-side server issue for loops involving things like sub.stream.submissions() and sub.stream.comments().

I've heard from a few people new to bot scripting that their continuous uptime worker scripts will stop running due to persistent Reddit-side server issues they can't get around. This format has worked for me for a while, hopefully it helps a few others.

import prawcore.exceptions
import time
... *other packages*

while True:
    try:
        for submission in subreddit.stream.submissions():
            # do something with submission ...

    except prawcore.exceptions.ServerError as e:
        print(f"A Reddit server error occurred: [{e}]. Sleeping before trying again...")
        time.sleep(60)
        pass

    except Exception as e:
        print(f'An unknown error occurred: [{e}]')
        raise

Sample Output:

A Reddit server error occurred: [received 502 HTTP response]. Sleeping before trying again...

This additionally works for any other non-critical error that you would like to trigger a restart of the script. You would just replace prawcore.exceptions.ErrorName with the correct error name you would like to consider.

If anyone has a more elegant way to error handling in their experience, let me know.
