I am trying to do the below in my track.json file , where each of the json file is a challenge track .  
"  
...  
"challenges": [  
{% include "challenges/indexing.json" %},  
{% include "challenges/restaurant\_autocomplete.json" %},  
{% include "challenges/tag\_autocomplete.json" %},  
{% include "challenges/area\_autocomplete.json" %},  
{% include "challenges/es\_primary\_search.json" %}  
]  
"

However, when I run it , I get an error saying ""Could not load '/Users/pgarg/src/personalizer-nightly-benchmarking/rally/track.json'", 'Expecting property name enclosed in double quotes: line 941 column 13 (char 27127)'". Could someone please help me in fixing it . Thank you

One addition: You don't need to include all of your challenges explicitly as there is a little helper in Rally, e.g.:

```auto
{% import "rally.helpers" as rally %}
{
 ...
  "challenges": [
    {{ rally.collect(parts="challenges/*.json") }}
  ]
}

```

Please see the [docs](http://esrally.readthedocs.io/en/stable/adding_tracks.html#structuring-your-track) for all details.
