SAP BTP Feature Flags Service instance access in NodeJs and deployment

[#1]

Hello SAP Gurus,

I have created one Feature Flags Service instance in BTP (featureflag). which i am trying to access in my Nodejs application using npm package @@sap/xsenv. which works fine in local run. I am getting all the details.

But problem occurs at the time of deployment. It does not recognize the feature-flags.

But we have the instance of feature-flags

Nodejs code -

var services = xsenv.getServices({
    "xsuaa": { name: 'basicnodejs-xsuaa' },
    "feature-flags": { name: 'featureflag' }
 });

Looking for help.
