ctx.author.edit(nick=...) error

[PyXiion]

Hello! I have a problem with changing the user's nickname. I did everything according to the documentation, but an error appears.
Code:

@bot.command()
async def nick(ctx, nick=None):
    if not nick:
        await ctx.message.add_reaction("❌")
        await ctx.send("...")
    elif check_nickname(nick):
        await ctx.message.add_reaction("❌")
        await ctx.send("...")
    else:
        await ctx.message.add_reaction("✅")
        await ctx.author.edit(nick=nick) #Error

Error:

Ignoring exception in command nick:
Traceback (most recent call last):
File "discord/ext/commands/core.py", line 85, in wrapped
ret = await coro(*args, **kwargs)
File "X.py", line 52, in nick
await ctx.author.edit(nick=nick)
File "discord/member.py", line 572, in edit
guild_id = self.guild.id
AttributeError: 'NoneType' object has no attribute 'id'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "discord/ext/commands/bot.py", line 935, in invoke
await ctx.command.invoke(ctx)
File "discord/ext/commands/core.py", line 863, in invoke

raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'NoneType' object has no attribute 'id'```

It's impossible for the library to give Member.guild a None value. Are you by any chance assigning member.guild = ... somewhere in the code?

[PyXiion]

No, I'm not changing member.guild. Although I may be wrong, but it seems that I did not change the member.guild

[AbstractUmbra]

Is this the full function that causes this issue? Perhaps if we could see the live code, if there is more?

[PyXiion]

Okay, here's the whole code. But such a problem is not only with this function, such a problem is almost everywhere where I try to get the guild

bot.py

intents = discord.Intents()
intents.messages = True
intents.reactions = True

    print("Bot started!")

    await bot.process_commands(message)
    if message.channel.id in VOTE_CHANNELS:
        await message.add_reaction("👍")
        await message.add_reaction("👎")
@bot.event
async def on_member_join(member):
    if check_nickname(member.name):
        await member.edit(nick=NOT_ALLOWED_NICK['change_to']) #Error
        await member.send(content=NOT_ALLOWED_NICK['message']['content'], \
            embed=NOT_ALLOWED_NICK['message']['embed'])

@bot.command() #Ok

    await ctx.send("Pong! " + " ".join(args))

    emb = discord.Embed(description=f"Приглашение: {invite}")
    emb.colour = EMBED_COLOR
    await ctx.send(embed=emb)
@bot.command() 
async def server(ctx:commands.Context):
    emb = discord.Embed()
    guild:discord.Guild = ctx.author.guild

    created_at = guild.created_at.strftime("%d.%m.%Y %H:%M:%S") #Error

    emb.title = f"Информация о сервере \"{guild.name}\""
    emb.set_thumbnail(url=guild.icon)
    emb.add_field(name="Регион:", value=str(guild.region))
    emb.add_field(name="Участники:", value=f"{guild.member_count}")
    emb.add_field(name="Владелец:", value=f"{guild.owner.mention}")
    emb.add_field(name="Возраст сервера:", value=created_at)

    emb.set_footer(text=f"ID: {guild.id}")
    ctx.reply(embed=emb)


@bot.command()
async def nick(ctx, nick=None)
    if not nick: #Ok

        await ctx.send("...")
    else: #Error
        await ctx.message.add_reaction("✅")
        await ctx.author.edit(nick=nick)

The issue here is your Intents.
You currently only have messages and reactions intents. You will also need a few more, like guilds and others. Please read the docs on what you need if you aim to cherry pick?

If you aim to use the default intents (all of the non-privileged ones), you can just use intents = discord.Intents.default() instead.

[PyXiion]

Thank you

[imvaskel]

What is the code for check_nickname?

[PyXiion]

def check_nickname(nick, regex=re.compile(r"[^a-zа-я0-9.?!]")):
    return regex.match(nick.lower())
