No data from graphite-web

[nanowish]

Hi,

I use graphite-web (from last github commmit). When using graphite-cyanite as finder I can't get all data from graphite-web

In cassandra having some data like:
| 60480 | 10 | collectd.cl1-filer-big_intra.disk-drbd0.disk_octets.write | 1416087320 | [7.8023e+12]

When getting data from: http://******/render?target=collectd.cl1-filer-big_intra.disk-drbd0.disk_octets.write&format=json result is:
[{"target": "collectd.cl1-filer-big_intra.disk-drbd0.disk_octets.write", "datapoints": [[7802289115136.0, 1416087320], [null, 1416087330], [null, 1416087340], [null, 1416087350], [null, 1416087360], [null, 1416087370], [null, 1416087380], [null, 1416087390], [null, 1416087400], [null, 1416087410], [null, 1416087420], [null, 1416087430], [null, 1416087440], [null, 1416087450], [null, 1416087460], [null, 1416087470], [null, 1416087480], [null, 1416087490], [null, 1416087500], [null, 1416087510], [null, 1416087520]]}]

You can see only first data are not empty

In cyanite log:

This same for all metrics, first datapoint have values, others are empty
My setting work great with influxdb and finder for influxdb
