I want to make a command that makes my bot send a message to the mentioned person, but this one line of code keeps returning NoneType. how do i fix this?
user = client.get_user('user id')
get_ methods only work when the thing you're getting is already in the cache; you need to use fetch_user. As you mentioned it's a command, you should already be within an async function.
user = await client.fetch_user(USER_ID)
try:
await user.send(content="A direct message")
except discord.Forbidden:
# don't have permissions to dm the user
# they might have turned dms off from non-friends
# either pass/continue/return whatever is appropriate
You could also use get_user in tandem with fetch_user.
user = client.get_user(USER_ID)
if not user:
user = await client.fetch_user(USER_ID)
fetch_user makes an API call so if you're doing this regularly then you might have the user in the cache from an earlier fetch. We can use get first to try and limit the API calls (and also make the command process slightly quicker).
