Subject

I have installed Sonata into my project and it is working fine, but it caused some parent() calls in TWIG to fail on An exception has been thrown during the rendering of a template ("Warning: Array to string conversion").. I have tried to debug this, until I got to this line in TWIG, where TWIG expects a string, but is given this array:

array:8 [▼
  "name" => false
  "admin" => false
  "value" => null
  "edit" => "standard"
  "inline" => "natural"
  "field_description" => null
  "block_name" => false
  "options" => array:26 [▼
    "default_group" => "Orders"
    "html5_validate" => true
    "sort_admins" => false
    "confirm_exit" => true
    "js_debug" => false
    "skin" => "skin-black"
    "use_select2" => true
    "use_icheck" => true
    "use_bootlint" => false
    "use_stickyforms" => true
    "pager_links" => null
    "form_type" => "standard"
    "default_admin_route" => "show"
    "default_label_catalogue" => "SonataAdminBundle"
    "default_translation_domain" => null
    "default_icon" => "fas fa-folder"
    "dropdown_number_groups_per_colums" => 2
    "logo_content" => "all"
    "list_action_button_content" => "all"
    "lock_protection" => false
    "mosaic_background" => "bundles/sonataadmin/images/default_mosaic_image.png"
    "javascripts" => array:3 [▼
      0 => "bundles/sonataadmin/app.js"
      1 => "bundles/sonataform/app.js"
      2 => "bundles/shopsysadmin/js/admin.js"
    ]
    "stylesheets" => array:4 [▼
      0 => "bundles/sonataadmin/app.css"
      1 => "bundles/sonataform/app.css"
      2 => "bundles/sonataadmin/admin-lte-skins/skin-black.min.css"
      3 => "bundles/shopsysadmin/css/admin.css"
    ]
    "role_admin" => "ROLE_SONATA_ADMIN"
    "role_super_admin" => "ROLE_SUPER_ADMIN"
    "search" => true
  ]
]

Code that causes this in my application is a parent() call in this block

{% block form_widget_simple %}
    {% set attr = attr|merge({'class': (attr.class|default('') ~ ' input')|trim}) %}
    {{ parent('form_widget_simple') }}
    {{- block('appendix_block') -}}
{% endblock form_widget_simple %}

If I remove Sonata from bundles.php the problem disappears.

I have not been able to pinpoint this any further, but I expect that the array should not be part of that widget.
