Reading SAP BTP credential Store error in require('node-fetch')

[#1]

Hello

I am implementing the credential store service in a simple nodejs app to read the keys stored in a namespaces created in the instance of a SAP BTP Credential Store service.

I referred to the NodeJS sample program given here to read the data

I keep getting error while deploying my app to the CF due to an issue in the node-fetch module.

Code Example (NodeJS) - SAP Help Portal

My package.json looks like this

  "dependencies": {
    "express": "4.17.2",
    "jwt-decode": "^3.1.2",
    "@sap/xsenv": "^3.1.1",
    "node-fetch": "^3.2.0",
    "node-jose": "^0.3.0"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node server.js"
  },
  "engines": {
    "node": "^12.0.0"
  },

server.js

....
const fetch = require('node-fetch');
//Due to an error during the deployment I tried with following declaration but then i get further errors in the code to read the headers.
// const fetch = (...args) => import('node-fetch').then(({default: fetch}) => fetch(...args)...

As I understand from the question on the forum , require('node--fetch') is not supported for the node-fetch module but then I don''t understand how to proceed with the implementation of the credential stores

javascript - Error: require() of ES modules is not supported when importing node-fetch - Stack Overf...

Any pointers ?

Hello,

The issue is resolved after i changed the versions of the modules to following

node-fetch : '^2.6.7'
node-jose : '^2.1.0'

I would suggest you try NodeJS 14:

  "engines": {
    "node": "^14"
  },

Hello Gregor,

It didn't work even after changing the node engine version.

Any other suggestion ?
