Hi,
Im trying to register some acf fields inside a flexible content box programatically.
one of the flexible content items is a repeater field, intended to have image fields repeat inside of it. I’ve managed to pull the fields to the wordpress admin pages fine, however when clicking the ‘add image’ button on any of the image fields, no media picker window pops up and im left with an error in the console that reads

Uncaught TypeError: Cannot read property 'query' of undefined
    at i.addFrameStates (acf-input.min.js?ver=5.7.7:3)
    at initialize (acf-input.min.js?ver=5.7.7:3)
    at i.t (acf-input.min.js?ver=5.7.7:1)
    at i.acf.Model (acf-input.min.js?ver=5.7.7:1)
    at i [as constructor] (acf-input.min.js?ver=5.7.7:1)
    at new i (acf-input.min.js?ver=5.7.7:1)
    at Object.acf.newMediaPopup (acf-input.min.js?ver=5.7.7:3)
    at i.selectAttachment (acf-input.min.js?ver=5.7.7:2)
    at i.onClickAdd (acf-input.min.js?ver=5.7.7:2)
    at i.<anonymous> (acf-input.min.js?ver=5.7.7:1)

The code for the fields follows:

acf_add_local_field_group(array (
   'key' => 'site_content',
    'title' => 'Custom Content',
    //Flexible content field
    'fields' => array (
    	array (
    	'key' => 'flexi_fields',
    	'label' => 'Flexible Fields',
    	'name' => 'acf_flexi_fields',
    	'type' => 'flexible_content',
        'display' => 'block',
        'button_label' => 'Add Section',
        'menu_order' => 0,
        //Add flexi items to array
    	'layouts' => array (
         //Flexi item 1
         array (
           'key' => 'flexi_field_accordion',
           'name' => 'flexi_field_accordion',
           'label' => 'Accordion',
         ),
         //Flexi item 2
         array (
           'key' => 'flexi_field_slider',
           'name' => 'flexi_field_slider',
           'label' => 'Slider',
         )
      ),
    ),
  ),
   //location of fields
   'location' => array (
    array (
      array (
    	'param' => 'post_type',
    	'operator' => '==',
    	'value' => 'post'
    ),
   ),
  ),
 ));
}

//Field setup for slider
acf_add_local_field(array(
  //link to parent
  'parent' => 'flexi_fields',
  'parent_layout' => 'flexi_field_slider',

  //field settings
  'key' => 'slider_wrapper',
  'name' => 'slider_wrapper',
  'label' => 'Slider',
  'type' => 'repeater',
  'display' => 'row',
  'min' => '',
  'max' => '',
));

  //Image
  acf_add_local_field(array(
    //link to parent
    'parent' => 'slider_wrapper',

    //field settings
    'key' => 'slider_img',
    'name' => 'slider_img',
    'label' => 'Image',
    'instructions' => '',
    'type' => 'image',
    'return_format' => 'url',
  ));

Thanks for any help in advance, this one really has me stumped
