I am getting started with Litecoin so please bear with my question. So I have a local litecoin node running in my local system. So I am planning to use NodeJS to communicate with the Litecoin server.

I tried to use following two wrappers :

https://litecoin.info/index.php/Node-litecoin

https://www.npmjs.com/package/litecoin

However, I am getting the following error when trying to call any rpc method :

/usr/bin/node --inspect-brk=35916 server.js 

Debugger listening on ws://127.0.0.1:35916/71ccef6f-eac8-4bf5-9d07-b0a8b4e93528
For help, see: https://nodejs.org/en/docs/inspector

Debugger attached.

null: Object {host: "localhost", port: 19335, user: "paras", pass: "paras", network: "testnet", …}
null: Client {rpc: Client}
RESTful API server started on: 3005

Both the wrappers are giving me the same error.

litecoin.conf
server=1
testnet=1
rpcuser=paras
rpcpassword=paras

Can someone help me with this please?
