I’ve asked this in another post, but not sure if it’s not been noticed as this is a specific question.
I have device data I can query from my sonos, which appears to be json formatted. However I can not access it in the same way as you would from the $response variable. ie variable.item
Am I missing something, or is $response a special case?

It just performs a refresh to ensure the data is up to date. I’m not sure if that necessary.
Then it just reads the data from the device attributes and I try to pick the uri item from the json returned.
I don’t have a Sonos, so I may be of very little help here. I have to do an API call to my audio device (Kodi on a rPi) to get $response info. A quick google search does list an API for sonos. But I think I am missing the point of your question here.
The sonos is just background on what I’m doing - trying to code round the fact it wont speak text and resume.
The issue is with trying to extract the uri variable from the json string data in the example piston.
If the same data had been returned into $response, I could use $response.uri, but data.uri des not work.
Either
I’ve just found this

You will need to use a backslash \ to escape all {}\ characters in the JSON. Since all strings in webCoRE support { variableName } interpolated values it ends up trying to handle your JSON as if it were a webCoRE expression.
For example, { "response": { "version": "0.1" } } will need to be written as \{ "response": \{ "version": "0.1" \} \} . Then you should be able to use the Parse JSON string action and interact with the data via the $json system variable (e.g. $json.response.version ).
I’m not sure how to use the parse JSON string action? I’ve set up a test string (using { } as stated) Theres a json string command. I’ve had a play around, but don’t seem to get any values in $json.
dynamic foo;
foo = parseJson(data)
Or
you can also try
you might want to make your ‘data’ variable type dynamic
