I presume it came from this http feed:
{noformat}
- type: org.apache.brooklyn.core.sensor.http.HttpRequestSensor
brooklyn.config:
name: planeId
period: 5s
jsonPath: "$"
uri:
$brooklyn:formatString:
- "%s/v1/server/planeid"
- $brooklyn:attributeWhenReady("main.uri.public")
{noformat}
My guess is that the api returned {{null}}, but I've not yet tried writing a
unit test to reproduce.
I'd have expected this to return the json value of {{null}} if that's what the
value is.
