[Solved] Transform with JSONPATH not working? What am I doing wrong?

Setup, Configuration and Use Beginners
1

Hi there,

I’m trying to integrate JSON output from Snips in my openhab rules but somehow the transformation doesn’t seem to work.

The rule is the following:
var String intentName = transform("JSONPATH", "$.intent.intentName", Snips_Intent.state.toString)

And Snips_Intent.state.toString contains:

The rule should output
[ "domi:LampenAusSchalten" ]

But logInfo(“snips.rule”, "intent name: " + intentName) outputs:

As you can see it outputs the complete JSON again?
What’s wrong here? According to an online JSONPATH tester it should work?
Openhab Version 2.4

I dunno. I just did this and it works as expected.

@mhilbush that’s weird, I get: https://gist.github.com/solars/7391af3d6456411334f82a89e3ea49fb

I’m using the latest docker version, is there anything I need to get transform to work?

@mhilbush nevermind - I uninstalled the jsonpath service and reinstalled it, and it worked :confused:

That’s weird. But, it works now… :smile:
