I’ve never done this via the docs but can see from the GUI that its something like:
{
"entities": [
{
"array": [
{
"factor": 1
},
{
"factor": 2
},
{
"factor": 2
},
{
"factor": 4
}
]
}
],

"instanceId": "root.object",
"enabled": false,

}
}
(which is a run test payload for executing a specific (testing)-tranformer)
Hope this helps
