We are trying to fetch historics data from the facebook source. Historic preview returns data, but whenever we launch the historics task with a push to a ElasticSearch or S3 destination there are no data sent. (we are using the web UI, not the API)
The facebook source is tagged as actived in our sources.
We tried with a simple query stream like : facebook.message contains "Barack Obama"
Got many hits with the historic preview, but a historics query over the same period of time returned no data.
