Simple http binding and jsonpath problem

Setup, Configuration and Use Beginners

I want to create a graph with the current covid cases.
I wanted to do that with the http binding get JSON data from “https://coronavirus-19-api.herokuapp.com/all”

The format of the data is:
{“cases”:200071,“deaths”:8009,“recovered”:82813}

In the http cfg I added:

covidworldwide.url=https://coronavirus-19-api.herokuapp.com/all
covidworldwide.updateInterval=5000

In the corresponding .items file I have:

String covidcasesworld "Cases [%s]" {http="<[covidworldwide:5000:JSONPATH($.cases)]"}

Still, i get the full “{“cases”:200071,“deaths”:8009,“recovered”:82813}” back as String.

Probably a small mistake that Im making but what am I doing wrong here?

Thanks!

Have you installed the JSONPATH transformation service? It is an add-on.

Yeah… small mistake… worked immediately

Have to mention though that “obvious” things like that should also be mentioned in the http binding with 2 extra words if it includes example with jsonpath. I thought thats so common that its implemented anyhow.

Thanks again for your help!
