changes = {} ?

I have a handler to BigPanda that doesn’t seem to be getting called. When I checked the logs I see this message:

sensu-server.log:{“timestamp”:“2016-08-17T14:49:59.969582+0000”,“level”:“warn”,“message”:“config file applied changes”,“file”:"/etc/sensu/conf.d/handlers/handler_bigpanda.json",“changes”:{}}`

Is this saying that the JSON file was read and nothing was applied since the changes are empty ("{}")?
