Json format issue when comes from Google Analytics

[Anonymous]

I try to add a JSON file in the repository. This Json file comes from Google Analytics API.
This file is well formed but I can declare it in the directory due to the error ""{0}" is not found or the json format is incorrect."
Please find below the content of my Json file.
{
"kind": "analytics#gaData",
"id": " https://www.googleapis.com/analytics/v3/data/ga?ids=ga:xxxx&dimensions=ga:medium,ga:source&metrics=g...",

Probably you can avoid parsing it by using the tGoogleAnalyticsInput component from talend exchange:
http://www.talendforge.org/exchange/index.php?eid=537&product=tos&action=view&nav=0,1,1
This component use the Java API to Google Analytics and parse everything for you.
The next advantage is, you don't have to define for every query a new json metadata schema.
