[SOLVED][1.12.2] The received string length is longer than maximum allowed 29 > 20

[AlexCreeper25]

So I made a small collection of mods to play with a friend of mine. I set up a forge server and everything's fine until i try to join the game. As the title says, I'm getting a "The received string length is longer than maximum allowed 29 > 20" error. I am using the latest forge 2847 on both client and server.

I've already done loads of research but it always lead to bukkit/spigot related bugs.

Here's my mods list:

If you need any other info tell me. I also use some client side mods like Optifine, journeymap, betterfoliage, sound filter, mo' bends and wawla

 

EDIT:  it looks like i cant upload the debug.log, it gives a -200 error 

Edited November 11, 2019 by AlexCreeper25
included more info

[DaemonUmbra]

Please provide debug.log from both client and server using one of the sites listed in my signature below

[AlexCreeper25]

Is it normal that it's taking a while to load the client's debug.log? The page even stops responding...

 

Btw here's the debug.log of the server:

https://paste.gg/p/anonymous/9cba97c03d814f48a5d7ba7b564fdf33

 

Imma try again with the client debug file

 

[AlexCreeper25]

Ok so i found out that there's a continuosly reported error in the client debug file, which you can view here:

https://paste.gg/p/anonymous/739997b433914d9d8cb7e3799081adfc

 

I didnt manage to upload the full debug.log client file anywhere even on gist. It's like 19 MB of stuff.

[AlexCreeper25]

Alright imma take a look thank you although it didn't give any problems before 

 

 

Edited November 11, 2019 by AlexCreeper25

[AlexCreeper25]

Nevermind it's still happening, same error as before

 

 

[AlexCreeper25]

So the error is still the same

 

New client debug.log, this time is full.

New server debug.log

Edited November 11, 2019 by AlexCreeper25

[AlexCreeper25]

Alright then Imma do it thank you for your help!

Edited November 11, 2019 by AlexCreeper25

[AlexCreeper25]

So, I managed to fix the issue, which is apparently caused by Wesley's Roguelike dungeons mod. Thank you everyone for the help!
