Here is the code:
{% for i in (0..5) %}
{% assign product = recommendations.top_related_products_{{i}}.products[0].title %}
{{ product }}
{% endfor %}
This code throws the error Liquid error: Cannot read property '0' of null
I have 6 arrays under recommendation like top_related_products_0...5
.
How do I print the title variable which is inside the top_related_products_0..5
?

Create a string containing the variable name, then use square bracket notation to access it.
For example:
{% for i in (0..5) %}
{% capture related_products %}top_related_products_{{i}}{% endcapture %}
{{ recommendations[related_products].products.first.title }}
{% endfor %}
