want to set of session variable one parameter string value to null

[PK_10315615]

Tring to set value of bsl as null but other properties values like temperature or owner should remain same in session.

this is the session input:

{"containerListFilters":{"location":[],"temperature":[{"array": [{"list_id": 1,"list_name": "RT"}]}],"owner":[], "bsl":[{"array": [{"list_id": 1,"list_name": "BSL 1"}]}]}}

output should be:

{"containerListFilters":{"location":[],"temperature":[{"array": [{"list_id": 1,"list_name": "RT"}]}],"owner":[], "bsl":[{"array": []}}

how can write the code for this?

Hi @PK_10315615 

Don't know how setting a JSON element is related to session parameter but you can create a custom JS service in ThingWorx with a JSON input say called "input" and output as JSON

input.containerListFilters.bsl[0].array = [];
result = input;
