Discord.py copy and paste channels command

    @commands.command()
    @commands.has_guild_permissions(administrator=True)
    async def copy(self, ctx):
        if str(ctx.author.id) not in Server.server_data:
            Server.server_data[str(ctx.author.id)] = Server.create_new_data()
        if str(ctx.author.id) in Server.server_data:
            Server.server_data[str(ctx.author.id)] = Server.create_new_data()
        
        channels = ctx.guild.text_channels
        Server.server_data[str(ctx.author.id)]["Channels"].append(str(channels))
        embed=discord.Embed(color=discord.Color.blue(), description = f"{ctx.guild.name}'s channels has been saved.")
        await ctx.send(embed=embed)

    @commands.command()
    @commands.has_guild_permissions(administrator=True)
    async def paste(self, ctx):
        embed=discord.Embed(color=discord.Color.blue(), description = "All channels have been pasted")
        channel = Server.server_data[str(ctx.author.id)]["Channels"]
        await ctx.guild.create_text_channel(channel)
        await ctx.send(embed=embed)

So I am trying to make a command for pasting the channels into a empty backup server but when do s!paste it sends an error message, which I tried to fix for a while but nothing is working.
