Issue with Accessing Nested Array(JSON handler) in Quickbase Pipeline

The easiest is to use a for loop. Depending on your use case, this may not be what you're after. 

{% for mod in b.modules %}
  mod.code
{% endfor %}

A use case I'm working with is fetching a report from quickbase, then iterating over the results. Each row returned has an array of locations (similar to modules). Using two different fields, I capture all the locations returned, and then grab the last one based on the loop index within the for loop. Hope this helps. 

{# code for locations field #}
{% set vals = namespace(value=[]) %}
{% for val in d.n19.value %}
  {% set vals.value = vals.value | append(val) %}
{% endfor %}
{{ vals.value | join("; ") }}

Which produces the values in the record as:

Grabbing just the last value in the array:

{# one value in locations - example #}
{% for val in d.n19.value %}
{% if loop.last %}
  {{ val }}
{% endif %}
{% endfor %}

Which produces the value in the record as:
