KLS crashes after rpc connections

[Rockenstien]

I am using Monaco Editor, So i am making calls to json rpc of KLS using websockets. But After these messages from server

 main      Kotlin Language Server: Version 1.4.0
 main      Connected to client
 async0    Adding workspace folder file:///root/language-server/monaco-languageclient/packages/examples/client/tmp
 async0    Adding .../tmp/tmp.kt, .../tmp/main.kt under /root/language-server/monaco-languageclient/packages/examples/client/tmp to source path

The server crashes and gives this error
