Description

When trying to retrieve the user id of the response metadata of a message, it returns user_id is not the valid attribute of the object.

Changes

There is a valid user id attribute in the class already, which is _user_id. I suspect it was just a typo.

    msg: interactions.Message = await ctx.channel.fetch_message(integer)
    msg_ref: interactions.Message = msg.interaction_metadata
    if msg_ref:
        print(msg_ref)
        await ctx.send(f"replied to {msg_ref.user}")
    else:
        await ctx.send("This message does not have a reference")
