Unable to accept friend requests

[WifiRouterYT]

Summary

As the title states, I'm unable to accept friend requests programatically.

Reproduction Steps

1. Add the following code to your main client class:

   async def on_relationship_add(self, relationship):
       if relationship.type == discord.RelationshipType.incoming_request:
           await relationship.accept()

2. Send a friend request to your bot
3. Receive a Bad Request (http code 400) in console.

Code

async def on_relationship_add(self, relationship):
    if relationship.type == discord.RelationshipType.incoming_request:
        await relationship.accept()

Expected Results

The friend request is automatically accepted.

Actual Results

Should be fixed now

the error shows up rarely now, but it still does not accept friend requests. ive tried a pip upgrade but no luck.
