Hello,

Try to replace the conditional with this: 

{%- capture contentForQuerystring -%}{{ content_for_header }}{%- endcapture -%}

{%- assign pageUrl = contentForQuerystring | split:'"pageurl":"' | last | split:'"' | first | split:'.com' | last | replace:'\/','/' | replace:'%20',' ' | replace:'\u0026','&'-%}

{% if pageUrl contains "?sort_by=created-descending" %}

    -----your stuff here----

{% endif %}

I hope it works!
