passing an array into hubl choice field

[asa_curry]

I am trying to build a choice field into a module that will let a user select a row from a hubdb table to pass into the module via a choice field. I have successfully built the loop to create the array, but the choice field rejects the input and I can't determine why. 

{% set table = hubdb_table_rows( XXXXXX ) %}

{% set sections = [] %}

{% for row in table %}
{{ sections.append(row.content_id) }}
{% endfor %}

[asa_curry]

I'm sorry, that code was incomplete, the following is returning an invalid argument error: 

% set sections = [] %}

{% for row in table %}
{{ sections.append(row.content_id) }}
{% endfor %}

{% choice "sections_field" label="How many sections?", value="default", choices="{{ sections }}", export_to_template_context=True %}

Hi @asa_curry,

I think there is issue with type of variable used for choices,  Instead of array use string variable and append string in it. and after that assign to choices attribute.
