  • have you given permissions in your controller? – sheraz khan Oct 31 '18 at 12:36
  • This is default magento customer module, you can check the same in your existing application. – Ranjeet Singh Oct 31 '18 at 12:45
  • After creating role and user, have you run command like caching, indexing? – Dhiren Vasoya Oct 31 '18 at 14:23

The above posted question is bug reproduced in Magento 2.2.x and it is throwing invalid parameter configuration provided for argument. The solution for the above issue is to add the code in file endor/magento/framework/View/Element/UiComponentFactory.php after line 149.

if (isset($componentArguments['block']) && !$componentArguments['block']) {
            return null;
        }

  • But Here a new challenge that how to override the above file. – Ranjeet Singh Nov 1 '18 at 16:05
  • Can you please update your question instead of answering? – sv3n Nov 1 '18 at 16:16
  • @sv3n Question is as it is what I was facing the problem. On searching I have found a temporary solution to edit core file and this will also fix in magento new release. But right now instead of editing core file I am trying to find some way to override the file. – Ranjeet Singh Nov 1 '18 at 16:27
