I am trying to use the code below and while using apps script it gives me the error, described below:

"TypeError: Cannot read property "date_config" from undefined."

My code looks like that:

function getConfig() {
  var config = cc.getConfig();
  config.setDateRangeRequired(true);
  config
    .newSelectSingle()
    .setId('date_config')
    .setName('Select date preset')
    .setHelpText('Select the date preset for which you would like to receive the ads data.')
    .setAllowOverride(true)
    .addOption(config.newOptionBuilder().setLabel('Today').setValue('today'))
    .addOption(config.newOptionBuilder().setLabel('Yesterday').setValue('yesterday'))
    .addOption(config.newOptionBuilder().setLabel('This week (Sunday to today)').setValue('this_week_sun_today'))
    .addOption(config.newOptionBuilder().setLabel('Last week (Sunday to Saturday)').setValue('last_week_sun_sat'))
    .addOption(config.newOptionBuilder().setLabel('Last week (Monday to Sunday)').setValue('last_week_mon_sun'))
    .addOption(config.newOptionBuilder().setLabel('This month').setValue('this_month'))
    .addOption(config.newOptionBuilder().setLabel('Last month').setValue('last_month'))
    .addOption(config.newOptionBuilder().setLabel('This quarter').setValue('this_quarter'))
    .addOption(config.newOptionBuilder().setLabel('Last three days').setValue('last_3d'))
    .addOption(config.newOptionBuilder().setLabel('Last seven days').setValue('last_7d'))
    .addOption(config.newOptionBuilder().setLabel('Last 28 days').setValue('last_28d'))
    .addOption(config.newOptionBuilder().setLabel('Last 30 days').setValue('last_30d'))
    .addOption(config.newOptionBuilder().setLabel('Last 90 days').setValue('last_90d'))
    .addOption(config.newOptionBuilder().setLabel('This year').setValue('this_year'))
    .addOption(config.newOptionBuilder().setLabel('Last year').setValue('last_year'))
    .addOption(config.newOptionBuilder().setLabel('Maximum').setValue('maximum'))

  return config.build();
}
