  .then(function(response) {
    console.log(response.json());});

response.json() in node-fetch library also returns a promise, instead try

fetch('someurltoAJsonFile.json')
  .then(response => response.json())
  .then(data => {
    console.log(data)
  });

you can look up more details about it here

EDIT:

It seems that the returned response wasn't in the valid json, so for the sake of completeness here is a code for text

fetch('someurltoAJsonFile.json')
  .then(response => response.text())
  .then(data => {
    console.log(data)
  });
