panic: interface conversion: interface is nil, not float64

[nhproject]

Hi

I'm using Kapacitor 0.12.0,
I recently started to get panic errors with Kapacitor:

panic: interface conversion: interface is nil, not float64

goroutine 296 [running]:
panic(0xc19100, 0xc827ebe340)
    /usr/local/go/src/runtime/panic.go:464 +0x3e6

created by github.com/influxdata/kapacitor.(*node).start
    /tmp/kapacitor/src/github.com/influxdata/kapacitor/node.go:129 +0x53

where afterwards Kapacitor stops.

Any idea why is it happening?
