Fetch request to VRO (orchestrator)

Help me, please, I really stuck in!

My task is to make up a react.js application that could request VRO via API and print getting data in the web interface.

I've created some Node.js class and can use "node-fetch" library for executing such requests, but when I try to use window.fetch I get

different error messages like these:

1. Access to fetch at 'https://hplab-vro.hplab.ix:8281/vco/api/versions/' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

My solution: insert {mode: 'no-cors'} in Fetch options.

The error disapears, but I get the second error.

2. Cross-Origin Read Blocking (CORB) blocked cross-origin response https://hplab-vro.hplab.ix:8281/vco/api/versions/ with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.

My JS code for executing Fetch to VRO:

const apiUrl = 'https://hplab-vro.hplab.ix:8281/vco/api/versions/';

const param = {

   method: 'GET',

   mode: 'no-cors',

   headers: {

   'Accept': '*/*',

   },

};

fetch (apiUrl, param)

  .then(response => response.json())

  .then(json => console.log(json));

Folks, have you got any guesses how to win this struggle? It makes me crazy!

Thanks in advance!
