Template Troubleshooting

When using a Metadata template or NTP Job template, the following scenarios can occur:

Problem at Job validation

Validation warnings:

|| entity.attributes.en_US.Licensing_Window_End

{% if entity.attributes['en_US']['APPCHA Licensing Window Start']
      || entity.attributes['en_US']['APPCHA Licensing Window End'] %}
{% endif %}

Solution

{% if entity.attributes['en_US']['APPCHA Licensing Window Start']
      or entity.attributes['en_US']['APPCHA Licensing Window End'] %}
{% endif %}

Cause

|| is not a supported LiquidJS logic operator.

There are 2 types of LiquidJS operators Operators | LiquidJS supported:
Comparison operators: ==, !=, >, <, >=, <=
Logic operators: or, and

Problem at Job validation

Pop-up error
unexpected token at "OR entity.att...", line:2, col:1

{% if entity.attributes['en_US']['Role'] OR entity.attributes['en_US']['Cast'] %}
{% endif %}

Solution

{% if entity.attributes['en_US']['Role'] or entity.attributes['en_US']['Cast'] %}
{% endif %}

Cause

OR is not a supported LiquidJS logic operator.

Problem at Job validation

Validation warnings:
The following attribute(s) have not been defined

'Category' | escape for UPTV Apple Episode 1

{% for category in entity.attributes['en_US']['Category' | escape ] %}
<App_Data App="MOD" Name="Category" Value="{{category}}"/>
{% endfor %}

Solution

{% for category in entity.attributes['en_US']['Category'] | escape %}
<App_Data App="MOD" Name="Category" Value="{{category}}"/>
{% endfor %}

Cause
Wrong LiquidJS syntax. escape is a filter that needs entity.attributes['en_US']['Category'] as input string.

Problem at Job validation

Pop-up error
illegal tag: {% for IMDB ID in entity.attributes['en_US']['PRIME IMDB ID'] %}, line:5, col:1

{% for IMDB ID in entity.attributes['en_US']['PRIME IMDB ID'] %}
    <IMDB>{{IMDB ID}}</IMDB>
{% endfor %}

Solution

{% for IMDBID in entity.attributes['en_US']['PRIME IMDB ID'] %}
    <IMDB>{{IMDBID}}</IMDB>
{% endfor %}

Cause

Wrong LiquidJS syntax. The for variable name must be a valid one.

size

{% if entity.attributes['en_US']['Actors'].size > 0 %}
    <credit role="actor">
    {% for actor in entity.attributes['en_US']['Actors'] %}
        <name>{{actor}}</name>
    {% endfor %}
    </credit>
{% endif %}

Solution

{% assign actorsArraySize = entity.attributes['en_US']['Actors'] | size %}
{% if actorsArraySize > 0 %}
    <credit role="actor">
    {% for actor in entity.attributes['en_US']['Actors'] %}
        <name>{{actor}}</name>
    {% endfor %}
    </credit>
{% endif %}

Cause

You can not use filters with dot notation. Use the pipe notation instead.

For example: collection.size is not supported. Use collection | size instead.

Problem at Job validation

Pop-up error
unexpected token at "> 0", line:1, col:1

{% if entity.attributes['en_US']['Actors'] | size > 0 %}
    <credit role="actor">
    {% for actor in entity.attributes['en_US']['Actors'] %}
        <name>{{actor}}</name>
    {% endfor %}
    </credit>
{% endif %}

Solution

{% assign actorsArraySize = entity.attributes['en_US']['Actors'] | size %}
{% if actorsArraySize > 0 %}
    <credit role="actor">
    {% for actor in entity.attributes['en_US']['Actors'] %}
        <name>{{actor}}</name>
    {% endfor %}
    </credit>
{% endif %}

Cause

You can not use filters with pipe notation inside a LiquidJS tag (operation). Save the collection size separately, in a variable and then use it.
{% assign size = collection | size %}

Problem

(1) value not populated for

entity.attributes['en_US']['MovieRatingADI']

entity.attributes['en_US']['Movie_HD']['properties']['format']['duration']

entity.attributes['en_US']['RatingMPAA-TV']

entity.attributes['en_US']['Episode_HD']['properties']['format']['duration']

when occurred in Metadata template

(2) Validation error at Job validation when occurred in NTP Job template

Validation errors:

undefined variable: MovieRatingADI, line:0, col:2, line:5, col:3

{% if entity.attributes['en_US']['EpisodeNumber'] != "" %}
  {% assign parentalValue = entity.attributes['en_US']['MovieRatingADI'] %}
  {% assign assetLengthValue = entity.attributes['en_US']['Movie_HD']['properties']['format']['duration'] | round %}
  {% assign fileNameValue = "Movie_HD" %}
{% else %}
  {% assign parentalValue = entity.attributes['en_US']['RatingMPAA-TV'] %}
  {% assign assetLengthValue = entity.attributes['en_US']['Episode_HD']['properties']['format']['duration'] | round %}
  {% assign fileNameValue = "Episode_HD" %}
{% endif %}

Solution

{% assign parentalValueMovie = entity.attributes['en_US']['MovieRatingADI'] %}
{% assign assetLengthValueMovie = entity.attributes['en_US']['Movie_HD']['properties']['format']['duration'] | round %}
{% assign parentalValueEpisode = entity.attributes['en_US']['RatingMPAA-TV'] %}

  {% assign fileNameValue = "Movie_HD" %}
{% else %}
  {% assign parentalValue = parentalValueEpisode %}
  {% assign assetLengthValue = assetLengthValueEpisode %}
  {% assign fileNameValue = "Episode_HD" %}
{% endif %}

Cause

If inside the for/if/elsif/else body there are reference paths (found as LiquidJS output values, or in any operations e.g. assign/for/if/elsif/else etc.), that have not been used outside it (this is their first appearance), these reference paths will not be solved with data fetched from our application.

In order to be populated with data from our application, the syntax reference must:

have one appearance outside an operation (where operation can be a for/if/elsif/else/capture etc.)
be the collection iterated inside the for operation

{% for adBreak in entity.tags['MOV_Feature_HD'].userProperties.adBreaks %}
    {{adBreak.timecode}}
{% endfor %}

be the condition used in if

{% if entity.attributes['en_US']['Trailer_TimedText']['filename']%}
  {{entity.attributes['en_US']['Trailer_TimedText']['filename']}}
{% endif %}

{% if entity.attributes['en_US']['Role'] and entity.attributes['en_US']['Cast'] %}
  {{entity.attributes['en_US']['Role']}}
  {{entity.attributes['en_US']['Cast']}}
{% endif %}

Problem

(1) value not populated for entity.attributes['en_US']['Trailer HD']['md5'] when occurred in Metadata template

(2) Validation error at Job validation when occurred in NTP Job template
