grc.imagemosaics.getGranules() fails without error message

[JakobMiksch]

const result = await grc.imagemosaics.getGranules(workspace, covStore, coverage);

• Fails for an existing and working URL without error message
• Credentials are set correctly.
• Other GET requests work fine.
• GeoServer version 2.21.0.
• geoserver-node-client version 1.1.0

Running an minimal example shows the same problem.

import fetch from 'node-fetch';

(async () => {
   const url = 'http://localhost:8080/geoserver/rest/workspaces/klips/coveragestores/foo/coverages/jm-mosaic/index/granules.json';
   const response = await fetch(url, {
       credentials: 'include',
       method: 'GET',
       headers: {
           'Authorization': 'Basic ????'
       }
   });
   console.log('Before JSON');
   const result = await response.json();
   //                                                                     <-- THE PROGRAM STOPS HERE WITHOUT ERROR message
   console.log('After JSON');
   console.log(result);    
})();

Interestingly when node-fetch v3 is used. The program still fails but throws this error message:

file:///..../geoserver-node-client/node_modules/node-fetch/src/body.js:234
                const error_ = error instanceof FetchBaseError ? error : new FetchError(`Invalid response body while trying to fetch ${data.url}: ${error.message}`, 'system', error);
                                                                         ^

Calling the same URL with axios works fine:

import axios from 'axios';

(async () => {
   var config = {
    method: 'get',
    url: 'http://localhost:8080/geoserver/rest/workspaces/klips/coveragestores/foo/coverages/jm-mosaic/index/granules.json',
    headers: {
        'Authorization': 'Basic ????'
    }
    };

    axios(config)
    .then(function (response) {
    console.log(JSON.stringify(response.data));
    })
    .catch(function (error) {
    console.log(error);
    });
})();

Update 2022-07-05

It seems to be a problem of GeoServer 2.21.0. I tested it with GeoServer 2.20.5, there the function runs like it should.
