java.lang.IndexOutOfBoundsException when saving some commands in command blocks

Resolved
Awaiting Response

This only applies on Multiplayer servers.

When this command:

[media]

is put into a command block while on a server, the client who put it gets kicked with this message:

Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException; readerIndex(1) + length(1) exceeds writerIndex(1): UnpooledHeapByteBuf(ridx: 1, widx: 1, cap: 1)

I can rejoin the server as after I get kicked

That happens with some other command too.

Mind checking how long it is? Command blocks have a character limit, and the game doesn't allow bypassing that limit.

32206.

Right, should be in bounds. (I'm on an I pad, so I don't have a way to count the characters in seconds.)

Forgot to mention that I can rejoin the server instantly after.

Could you attach the log files of both the server and client? (you can blank out the IPs if you want.)

Characters, yes, bytes, no.
A single character may require multiple bytes.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w43a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

This is still here up through 1.11.
Note that affected commands only throw an error in multiplayer, and in singleplayer (even LAN), the command is accepted. As for the provided command, it doesn't use any extra-bytes characters, so that isn't it.

I can confirm for either 1.12.2 and 1.13

Please check if that's still an issue for you in the latest 1.16.5 stable release or the latest 1.17 development snapshot.
