web_reg_save_param_json retruns string not found

VUGEN version: 2023 R1 build 251

Protocol: HTTP/HTML using C

I'm trying to get values based a condition that a specific property doesn't exist. The query works in online tools like https://jsonpath.com/ but the same query is not working in VUGEN.

Example:

{
"data": {
"items": [
{
"status": "SUCCESS",
"id": "2edxxxx-18cd-4afd-587d-08dcbe08bd22"
},
{
"status": "SUCCESS",
"filePath": "xyz",
"id": "101xxxx-3719-4c18-15cc-08dcbc8db422"
}
]
},
"statusCode": 200
}


I need to get the value of id if the filePath property doesn't exist. The queries that I used is below. both are working in online tools.

$.data.items[?(!@.filePath)].id
$.data.items[?(@.filePath==null)].id


Action.c(17): Error: No matches were found for the specified query: "$.data.items[?(!@.filePath).id".
Action.c(17): Error: lr_json_find failed

I tried using both  lr_json_find and web_reg_save_param_json, no luck.

Is there an updated jsonparser.dll that handle these types of queries?
