JsonPath cannot create a new path if doesn't exists

[pyus13]

Eg the Json is

val myJson = "properties" : {
}

val json = JsonPath.parse(myJson).set("$.properties.image.source", "my_image_url").jsonString()

Log.d("", "JSON UPDATED $json")

returns

"properties" : {
}

instead of

"properties" : {
    "image" :{
        "source" : "my_image_url" 
    }
}

The test method in Kotlin.

 @Test
 fun testJsonPathSet() {
        val jsonString = "{\"properties\": {}}"
        val newJson = JsonPath.parse(jsonString).set("$.properties.image.source", "image_url").jsonString()
        val expectedNewJson = "{\"properties\":{\"image\":{\"source\":\"image_url\"}}}"
        Assert.assertEquals(expectedNewJson, newJson)
    }

@pyus-13 set function only could change the value whith the path exists. If you want to add a new path, you could use put function to achive it.
In your case, you could write like this:

    String json = "{\"properties\": {}}";
    DocumentContext context = JsonPath.parse(json);

    context.put("$.properties", "image", new HashMap<>());   // add a new path "$.properties.image"
    context.put("$.properties.image", "source","image_url"); // continue to add a new path "$.properties.image.source"
    String newJson = context.jsonString();
    String expectedNewJson = "{\"properties\":{\"image\":{\"source\":\"image_url\"}}}";

    Assert.assertEquals(expectedNewJson, newJson);
