String jsonResponse = """
[
    {
        "vi": ["Khoá đào tạo miễn phí", 4],
        "en": ["Free training courses", 4]
    },
    {
        "vi": ["Miễn phí giao hàng", 2],
        "en": ["Free delivery", 2],
    }
]
""";

From the JSON response above I need to get the values of the key “vi” then store them in a List<String, Object>.

I’ve tried using $..vi in https://jsonpath.com/ and got the correct result.

When trying the Java code below, however, I always get Exception in thread “main” java.lang.IllegalArgumentException: The parameter “vi” was used but not defined. Define parameters using the JsonPath.params(…) function.

JsonPath jsonPath = JsonPath.from(jsonResponse);
List<Map<String, Object>> perks = jsonPath.get("$..vi");

I do know that RestAssured in Java uses Gpath notation but I’m stuck on how to get my code working.

I’m using Java RestAssured and Jackson API.
