Couldn't handle packet of type CHANNEL_DELETE

You're not getting any other errors before this, right?

[MedicOP]

Nope

[Bastian]

Hmm, that's strange...
Do you get this error message regularly or was this the only time?

[MedicOP]

Regularly. My bot deletes voice channels if they are left empty for 30 seconds

[Bastian]

Is the bot, which deletes the channels, the same not which throws the exception?

[MedicOP]

Yes, it is.

2.0.15 has started producing random warnings like this for me as well. Upon channel connect I get

WARN de.btobastian.javacord.utils.PacketHandler - Couldn't handle packet of type GUILD_CREATE.

Reverting back to 2.0.14 solves the issue. 👍

It seems like calling VoiceChannel.delete() removes the channel from the cache. Then when a CHANNEL_DELETE packet is received, it tries to remove it again causing NPE because it's not in the cache anymore.

Could either remove the code in VoiceChannel.delete() that removes it from the cache and just rely on the packet listener instead, or just add a null check in ChannelDeleteHandler.handle

I easily recreated this in the newest version,
@Command(aliases = "!test") public String test(Channel channel){ channel.delete(); return null; }

@MedicOP
Yes, that's most likely the issue.

@ryleykimmel
Can you please show me the full error message? It's another packet, so these two issues aren't related.

[Bastian]

Fixed :)
