action expandVar is not working for objects non stringified

[AlvaroVega]

When object is a part of a string to be expanded

i.e.:

"subject": "the id ${id} of type ${type} has location ${location}"

Do you mean it works only when the whole string is the macro? I mean:

"subject": "${id}"

[AlvaroVega]

No, it works when macro is composed of several string vars like:

"subject": "the id ${id} of type ${type}"

but not works when one of these vars is a json object:

"subject": "the id ${id} of type ${type} has location ${location}"

but works when macro is just one json object: (fixed in #692)

"subject":"$location"

No new case is not working from #692

For example this action has a json attribute locationCopy which is not expanded

"action":{
        "type":"update",
        "parameters":{
            "id":"${id}_mirror",
            "version": 2,
            "attributes": [
                {
                    "name":"abnormal",
                    "type":"Number",
                    "value": 7
                },
                {
                   "name": "locationCopy",
                   "type": "MyCustomTypo",
                   "value": {
                       "type":"Point",
                       "coordinates":["${Lat}","${Lon}"]
                   }
              }
            ]
        }
    }

And the workaround needed is use a json stringifed value:

"action":{
        "type":"update",
        "parameters":{
            "id":"${id}_mirror",
            "version": 2,
            "attributes": [
                {
                    "name":"abnormal",
                    "type":"Number",
                    "value": 7
                },
                {
                   "name": "locationCopy",
                   "type": "MyCustomTypo",
                   "value": "{\"type\":\"Point\",\"coordinates\":[${Lat},${Lon}]}"
              }
            ]
        }
    }
