Google picker API error: Server IP address n-utbhwlxa4witl3o3ev4uschzd37oxgge2qt73xy-0lu-script.googleusercontent.com was not found

I have a problem with running Google picker API.

I'm trying to make a custom menu function for my Google spreadsheet that I can choose a file with (obtain file ID on Google Drive) and then my apps-script will automatically rename it according to result in some cell in sheet and then it will also move the file to a proper folder on Google Drive. I think I'm able to do everything mentioned above except to run Google picker API.

To do task described above I think I need Google Picker API. Please correct me if I'm wrong!!! I just need a dialog window which will let me choose a file and let give me file ID of the chosen file.

So basically I have followed instructions for File-open dialogs here and here. I've tried it many many times. I've tried every help I could find on youtube or google, but the result is still the same:

When I open my spreadsheet, I see my new custom menu, I open it and click on Start which runs the script. The script opens a blank window with "Select a file". After a while I get this statement:

The statement means "Server IP address n-utbhwlxa4witl3o3ev4uschzd37oxgge2qt73xy-0lu-script.googleusercontent.com was not found" (Address looks like Client ID, but it's definiteliy not the ID i see in web console.)

I've enabled Google Picker Api and Google drive API in developers console, I've also copied API_KEY to the code. I think I've done everything described in instuctions right. But I've done nothing more. I'm afraid that I'm missing some basic step which is obvious for skilled developer, but I've no clue. (Like if I have to specify Authorized JavaScript origins for OAuth 2.0 client IDs etc.)

Anybody any idea or direction, please?

EDIT: My .gs code is (copy-pasted from https://developers.google.com/apps-script/guides/dialogs):

    /**
     * Creates a custom menu in Google Sheets when the spreadsheet opens.
     */
    function onOpen() {
      SpreadsheetApp.getUi().createMenu('Picker')
          .addItem('Start', 'showPicker')
          .addToUi();
    }

    /**
     * Displays an HTML-service dialog in Google Sheets that contains client-side
     * JavaScript code for the Google Picker API.
     */
    function showPicker() {
      var html = HtmlService.createHtmlOutputFromFile('filepicker.html')
          .setWidth(600)
          .setHeight(425)
          .setSandboxMode(HtmlService.SandboxMode.IFRAME);
      SpreadsheetApp.getUi().showModalDialog(html, 'Select a file');
    }

    /**
     * Gets the user's OAuth 2.0 access token so that it can be passed to Picker.
     * This technique keeps Picker from needing to show its own authorization
     * dialog, but is only possible if the OAuth scope that Picker needs is
     * available in Apps Script. In this case, the function includes an unused call
     * to a DriveApp method to ensure that Apps Script requests access to all files
     * in the user's Drive.
     *
     * @return {string} The user's OAuth 2.0 access token.
     */
    function getOAuthToken() {
      DriveApp.getRootFolder();
      return ScriptApp.getOAuthToken();
    }

and my html code (also copy-pasted from the same source) is as follows (I have not changed anything except Developers key):

<!DOCTYPE html>

  <link rel="stylesheet" href="https://ssl.gstatic.com/docs/script/css/add-ons.css">

    // IMPORTANT: Replace the value for DEVELOPER_KEY with the API key obtained
    // from the Google Developers Console.
    var DEVELOPER_KEY = 'I put my own key here';
    var DIALOG_DIMENSIONS = {width: 600, height: 425};
    var pickerApiLoaded = false;

    /**
     * Loads the Google Picker API.
     */
    function onApiLoad() {
      gapi.load('picker', {'callback': function() {
        pickerApiLoaded = true;
      }});
     }

    /**

     * it can be passed to Picker. This technique keeps Picker from needing to

Fortunately, Amit Agarwal wrote a tutorial on this blog about using Picker API in Apps Script.

Here's a snippet:

function onOpen() {
  SpreadsheetApp.getUi().createMenu('Google Picker')
      .addItem('Choose Folder', 'showPicker')
      .addToUi();
}

/**
 * Displays an HTML-service dialog in Google Sheets that contains client-side
 * JavaScript code for the Google Picker API.
 */
function showPicker() {
  var html = HtmlService.createHtmlOutputFromFile('Picker.html')
      .setWidth(600)
      .setHeight(425)
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  SpreadsheetApp.getUi().showModalDialog(html, 'Select Folder');
}

function getOAuthToken() {
  DriveApp.getRootFolder();
  return ScriptApp.getOAuthToken();
}
