Liquid filters (specifically `absolute_url`) break build if used in the responsive image template

[jerturowetz]

If I try to use liquid filters in the responsive image template file I get the following error:

Liquid Exception: undefined method `config' for nil:NilClass in /_layouts/default.html

Example template file

The following are the contents of my template file. When I remove the | absolute_url filter everything works fine.

{% assign largest = resized | sort: 'width' | last %}
{% capture srcset %}
{% for i in resized %}
    /{{ i.path }} {{ i.width }}w,
{% endfor %}
    /{{ path }} {{ original.width }}w
{% endcapture %}

<img src="{{ path | absolute_url }}" alt="{{ alt }}" class="{{ class }}" srcset="{{ srcset | strip_newlines }}" sizes="{{ sizes }}" />

Expectations

Expected behaviour: Liquid filters accessible Actual behaviour: No worky

Hmm, this might be a tricky one. I don't have time to look into a proper fix right now, but I think you should be able to get around it by doing something like this instead:

{% assign url = path | absolute_url %}
<img src="{{ url }}">

I did not yet try that one, lemme give it a go and advise.

The suggested workaround did not work for me, but I was able to get a (fragile) solution with:

<img src="{{ site.url }}/{{ path }}" />
