I have found answer to my question problem was on service side:

I had not properly created a static folder which I later added following line

app.use(cors());
app.use('/image',express.static("uploads"));
app.use(bodyParser.json()); // to support JSON-encoded bodies
app.use(
 bodyParser.urlencoded({
   // to support URL-encoded bodies
   extended: false,
 })
);
