jquery.once is perfectly working, I placed console.log inside it, but I still get this error especially when I load the Views UI without even before I press any button
When I press any button, a progress animation appears and again this error appears
views-admin.js?op2hqg:164 Uncaught TypeError: $form.once is not a function at Object.Drupal.behaviors.addItemForm.attach (views-admin.js?op2hqg:164)
When I investigates I found that the following jquery select returns 0 objects
var $form = $(context).find('form[id^="views-ui-add-item-form"]').first();
How to solve this, should I disable any modules?
