Serverside information

Bot Location is 356.5 71.0 1155.5 Bot Gamemode is 3 (spectator mode)

Dimension type is minecraft:overworld Map seed is 1783548169946369349 I cannot provide you the entire map, sorry :(

Additional context

Cannot provide code, and not even related to my code. Copy pasted the example code and happened the same.

I have no idea how I should fix this, but I do know that I don't need chunk rendering and parsing, I just want it to read chat and response. It would be grateful if you make another version of API for people like me.

The error is not related with chunks in the minecraft sense. It's just a packet chunk. What kind of server is it ?

Some additional infos: The packet received (1a) is the "kick_disconnect" packet https://github.com/PrismarineJS/minecraft-data/blob/master/data/pc/1.16.1/protocol.json#L1776 The decoded reason string says: 

{"translate":"disconnect.genericReason","with":["Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(1) + length(1) exceeds writerIndex(1): PooledUnsafeDirectByteBuf(ridx: 1, widx: 1, cap: 1)"]}

The TypeError: Cannot read property 'length' of undefined error is a consequence of the packet not being decoded properly.

Karang commented 4 years ago

Since the server is kicking you because it fails to decode one of your packet. This could be coming from your code. Have you tried with one of the mineflayer example ?

CrackThrough commented 4 years ago

what, but my app got crashed for same error using one of mineflayer examples?

Copy pasted the example code and happened the same.

alright I will try to update mineflayer and everything related to this and try again soon. I will comment the result after this test.

Karang commented 4 years ago

@CrackThrough did you retry with updated mineflayer ?

CrackThrough commented 4 years ago

I will try to post result within a week. Sorry I don't really have much time often. :(

CrackThrough commented 4 years ago

Tested within same environment with the different map file (server's owner was not me and the server was temporary). Updated version of mineflayer didn't replicate the same error I was getting. My conclusion is something in the new update fixed this error, or it was my simple mistake I was not aware of. If someone else is having a same issue, you could update to new version or double check what you were doing.

Karang commented 4 years ago

Ok, thanks for the info.
