Marklogic node js client api not connecting to database - node.js

Question

I am trying to load some documents in my "Documents" database, but am getting this error on running node load.js(filename):
Error: read ECONNRESET
at TCP.onStreamRead (internal/stream_base_commons.js:201:27) {
errno: -4077,
code: 'ECONNRESET',
syscall: 'read'
}
load.js
// Load documents into the database.
const marklogic = require('marklogic');
const my = require('./my-connection.js');
const db = marklogic.createDatabaseClient(my.connInfo);
// Document descriptors to pass to write().
const documents = [
{ uri: '/gs/aardvark.json',
content: {
name: 'aardvark',
kind: 'mammal',
desc: 'The aardvark is a medium-sized burrowing, nocturnal mammal.'
}
},
{ uri: '/gs/bluebird.json',
content: {
name: 'bluebird',
kind: 'bird',
desc: 'The bluebird is a medium-sized, mostly insectivorous bird.'
}
},
{ uri: '/gs/cobra.json',
content: {
name: 'cobra',
kind: 'mammal',
desc: 'The cobra is a venomous, hooded snake of the family Elapidae.'
}
},
];
// Load the example documents into the database
db.documents.write(documents).result(
function(response) {
console.log('Loaded the following documents:');
response.documents.forEach( function(document) {
console.log(' ' + document.uri);
});
},
function(error) {
console.log(JSON.stringify(error, null, 2));
}
);
my-connection.js
module.exports = {
connInfo: {
host: 'localhost',
port: 8000,
user: 'user',
password: 'password'
}
};
