Why am I seeing 'Liquid error: Unknown operator blank' in my store search results?

[Fabian_weldon]

thanks for the response.

this is my entire product-grid-item.liquid:

{% comment %}

This snippet is used to showcase each product during the loop,
‘for product in collection.products’ in collection.liquid.

A liquid variable (grid_item_width) is set just before the this
snippet is included to change the size of the container.
Once the variable is set on a page, all future instances of this
snippet will use that width. Overwrite the variable to adjust this.

Example

• assign grid_item_width = ‘large–one-quarter medium–one-half’

{% endcomment %}

{% unless grid_item_width %}
{% assign grid_item_width = ‘large–one-third medium–one-half’ %}
{% endunless %}

{%- assign height = 415 -%}

{% if product.compare_at_price > product.price %}
{% assign on_sale = true %}
