I have an issue that when I put a command inside a command block that's 39000 characters long, the game crashes. More specifically it crashes when I click done.

COMMAND USED :

Here's an image of the error client side.

Here's a still image of the same error but as a still image in case you want to read it,

If you'd like to try it for yourself on your server to see it's the same then you can make a command here. https://bimbimma.com/minecraftmurals/ I used the default in this example.

Here's the server side error log

^21:50:56 [Error] io.netty.handler.codec.EncoderException: String too big (was 33684 bytes encoded, max 32767)
21:50:56 [Info] PLAYERNAME lost connection: Disconnected
21:50:56 [Info] PLAYERNAME left the game.^

Here is the error log on a vanilla server with no client mods or server plugins.

Something is added to the command when it runs on the server. I'd like to know what the changes are but commandBlockOutput dose not show the full command but just the parts of it.

The limit for single-player is 39000. the limit for servers is 31181 though. Any ideas would be much aprecu
