Trying to fetch or load attribute causes error.

[MrTransparentBox]

Whenever I try to load or fetch the author part of a submission (in order to get the "icon_img") for my discord.py bot, it gives an error. Interestingly the other parts are available without using .load(), but it wants me to fetch (or use .load()) in order to access author.icon_img or it says that icon_img doesn't exist.

To Reproduce
Steps to reproduce the behaviour:

1. Add that command to a discord bot
2. Run the "meme" command
3. Wait for the command to process
4. IndexError: list index out of range

Expected behavior
Allows me to get any information I wanted about the author. The submission info works, and most of the author info works, it's just the icon_img that is broken. It complains that attribute doesn't exist and suggests using .load(). When I do that it then gives an IndexError, the same occurs if I use fetch=True.

Maybe it's my mistake but can someone help.

I tried the following code and was not able to reproduce this.

import random
import discord
    
async def main():
    submissions = []
    reddit = asyncpraw.Reddit(**settings)
    sub = random.choice(["dankmemes", "memes"])
    subr = await reddit.subreddit(sub)
    async for item in subr.top("hour"):
        submissions.append(item)
    submission = random.choice(submissions)
    author = await reddit.redditor(name=submission.author.name)
    await author.load()
    emb = discord.Embed(title=submission.title, url=f"https://www.reddit.com{submission.permalink}", description="", color=discord.Color.random())
    emb.set_image(url=submission.url)
    emb.set_author(name=author.name, url=f"https://www.reddit.com/user/{author.name}", icon_url=author.icon_img)
    emb.set_footer(text=f"{':+1:'} {submission.score}  ||  {':speech_balloon:'} {submission.num_comments}  ||  Posted by {author.name}")

if __name__ == "__main__":
    loop.run_until_complete(main())

Could this be a problem with discord.py?

Possibly, some strange things are occurring when using async praw, that don't happen with the non-async version. E.g. I copied out the code you used for your test (obviously changing Reddit init, etc.) and began to get this error

I used this code:

    sub = random.choice(["memes", "dankmemes"])
    subr = await reddit.subreddit(sub)
    s = subr.top()
    async for i in s:
        submissions.append(i)

    submission = random.choice(submissions)
    author = await reddit.redditor(name=submission.author.name)
    await author.load()
    print(submission.title)
    print(submission.permalink)
    print(submission.url)
    print(author.name)
    print(author.icon_img)
    await asyncio.sleep(2)
    print("slept well")
    await asyncio.sleep(2)
def main():
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    loop.run_until_complete(meme())

main()

Although I've used discord.py for a while, using things in async is quite new to me, so I might have made a lot of mistakes.
Thanks for all your help @LilSpazJoekp.

I am not able to reproduce this bug with this environment:

System Info

• OS: macOS 11.1 (20C69)
• Python: 3.7.8
• Async PRAW Version: 7.1.1

This appears to be an issue with Microsoft Visual Studio. I have a couple of things you could try:

• You appear to be running it in debug mode, try executing the script normally.
• Try with Visual Studio Code.
• Try with the latest version of Python.

I'm going to close this issue due to inactivity. If you still need help feel free to comment or reopen this issue.
