python - 'NoneType' object has no attribute 'is_connected'

Question

i have wrote a bot to play music, but it always print and error:

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'NoneType' object has no attribute 'is_connected'

This is my function:

async def play(ctx, url):
if ctx.message.author.voice:
    channel = ctx.message.author.voice.channel
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if not voice.is_connected():
        await channel.connect()

I think the error is generated by this function:

voice.is_connected()

Dont know why it doesn't work ...

Answer 1

I think this would work

channel = ctx.message.author.voice.channel

        voice = discord.utils.get(ctx.guild.voice_channels, name=channel.name)

        voice_client = discord.utils.get(self.client.voice_clients, guild=ctx.guild)

        if voice_client == None:
            await voice.connect()
        else:
            await voice_client.move_to(channel)
