Python discord是在角色存在的时候不承认它

import discord
from discord import app_commands
import json

intents = discord.Intents().all()

client = discord.Client(intents=intents)

tree = app_commands.CommandTree(client)

@tree.command(name="subscribe")
async def the_command(interaction, itemid: str):
    discid = int(interaction.user.id)
    print(discid)

    with open("data.json", "r") as file:
        data = json.load(file)

    if itemid in data:
        role_id = data[itemid]["roleid"]
        print(role_id)

        guild = interaction.guild
        print(guild)
        member = await guild.fetch_member(discid)
        print(member)

        if member is not None:
            role = guild.get_role(role_id)

            if role is not None:
                await member.add_roles(role)
                await interaction.response.send_message(f"Role assigned for item ID: {itemid}")

            else:
                await interaction.response.send_message(f"Role for item ID {itemid} not found in the guild.")
        else:
            await interaction.response.send_message("You are not a member of this guild.")
    else:
        await interaction.response.send_message(f"Item ID {itemid} not found in the data.")

它返回的角色是NONE，说discord不承认它.

是的，我已经判断了unions 本身的ID，它是一个具有相同ID的现有角色，所以我很困惑

我做错什么了吗？
