Playlist playback error. Discord py. Youtube dl - discord

Question

I'm writing a Discord bot to play music
When trying to play a playlist, it throws the error 'Command raised an exception: KeyError: 'webpage_url'. What could be the problem?
It won't even load the first video
def __init__(self, ctx: commands.Context, source: discord.FFmpegPCMAudio, *, data: dict, volume: float = 0.5):
super().__init__(source, volume)
self.requester = ctx.author
self.channel = ctx.channel
self.data = data
self.title = data.get('title')
self.tags = data.get('tags')
self.url = data.get('webpage_url')
self.stream_url = data.get('url')
def __str__(self):
return '**{0.title}** by **{0.uploader}**'.format(self)
#classmethod
async def create_source(cls, ctx: commands.Context, search: str, *, loop: asyncio.BaseEventLoop = None):
loop = loop or asyncio.get_event_loop()
partial = functools.partial(cls.ytdl.extract_info, search, download=False, process=False)
data = await loop.run_in_executor(None, partial)
if data is None:
raise YTDLError('Couldn\'t find anything that matches `{}`'.format(search))
if 'entries' not in data:
process_info = data
else:
process_info = None
for entry in data['entries']:
if entry:
process_info = entry
break
if process_info is None:
raise YTDLError('Couldn\'t find anything that matches `{}`'.format(search))
webpage_url = process_info['webpage_url']
partial = functools.partial(cls.ytdl.extract_info, webpage_url, download=False)
processed_info = await loop.run_in_executor(None, partial)
if processed_info is None:
raise YTDLError('Couldn\'t fetch `{}`'.format(webpage_url))
if 'entries' not in processed_info:
info = processed_info
else:
info = None
while info is None:
try:
info = processed_info['entries'].pop(0)
except IndexError:
raise YTDLError('Couldn\'t retrieve any matches for `{}`'.format(webpage_url))
return cls(ctx, discord.FFmpegPCMAudio(info['url'], **cls.FFMPEG_OPTIONS), data=info)
