Attempted to call an undefined method named "macro_attributes" of class

[ducho]

Hi. I have problem with integration custom knpmenu template in Symfony 4.2. I still get this message: Attempted to call an undefined method named "macro_attributes" of class "__TwigTemplate_46b504049d303cbba60b9082144af113b977223be17dc1e45f9421ff99d7f8d3".

Can anybody help me?

This is my template:

{% extends 'knp_menu.html.twig' %}
{% block item %}
    {% import _self as knpmenu %}
    {% if item.displayed %}

        {%- set is_header = attributes.header|default(false) %}
        {%- set divider_prepend = attributes.divider_prepend|default(false) %}
        {%- set divider_append = attributes.divider_append|default(false) %}
        {%- set class = is_header ? 'header' : 'item' %}

        {# hide empty groups #}
        {%- if not (is_group and item.hasChildren == false) -%}
            {# unset bootstrap specific attributes #}
            {%- set attributes = attributes|merge({'group': null, 'header': null, 'divider_prepend': null, 'divider_append': null, 'class': class }) %}

            {#{%- if divider_prepend %}#}
                {#{{ block('dividerElement') }}#}
            {#{%- endif %}#}

Well, you use the knpmenu.attributes macro in many of your blocks. But only one of them imports the macro. I suspect that the error comes from another block. Does it work if you import the macro in each block needing it ?

[kaistaerk]

With importing in each block, it works
