The bot bans for a reason consisting of 1 word, how to fix it?

Question

Python

There is a code to ban a participant by ping or ID:

@bot.command()
@commands.has_guild_permissions(ban_members=True)
async def ban(ctx, member:discord.User=None, reason =None):
     if member == ctx.message.author:
         await ctx.channel.send("Жаль, но ты не можешь забанить себя :(")
         return

     if reason == None:
         reason = "Причина бана не указана"

     message = f"Вы были забанены на сервере **{ctx.guild.name}** по следующей причине: \n{reason}."

     await member.send(message)
     await ctx.guild.ban(member, reason=reason)

     embed = discord.Embed(
        title = 'Успешно!',
        description = f'{member} забанен по причине {reason} модератором {ctx.author.mention}!',
        colour = discord.Colour.from_rgb(0, 255, 0)
    )
     await ctx.send(embed=embed)
    
@ban.error
async def cmderr27262682919625141(ctx, error):
     if isinstance(error, commands.errors.MissingPermissions):
         await ctx.send(':x: У вас недостаточно прав!')

The code is fully working, there are no errors, but when I write !ban @ member reason,
the bot bans with the reason consisting of the 1st word of the reason, and then it seems that it does not see. How to fix it?
