QSE: GetSetAnalysis working but empty ?

[dvasseur]

HI,

I'm using the QSE JSON API to retrieve the bookmarks list of an app (GetBookmarks) and then I'm calling GetSetAnalysis on each bookmark to retrieve the selected values for each field. The GetSetAnalysis call itself is working, but the returned list is always empty. Checking the same app using Chrome dev tools and the websocket messages, the same call with the same params is returning the right values => I'm probably missing something, but what ?

GetBookmarks

call:
{"handle": 1, "method": "GetBookmarks", "params": {"qOptions": {"qTypes": ["bookmark"], "qData": {"title": "/qMetaDef/title", "sheetId": "/sheetId", "selectionFields": "/selectionFields", "creationDate": "/creationDate", "approved": "/approved", "published": "/published"}}}, "outKey": -1, "id": 2}

response (OK):
"jsonrpc":"2.0","id":2,"result":{"qList":[{"qInfo":{"qId":"ffff1727-97e8-440c-bd09-b9fa79af382e","qType":"bookmark"},"qMeta":{"title": ...

GetSetAnalysis:

call:
{"handle": 1, "method": "GetSetAnalysis", "params": ["$", "ffff1727-97e8-440c-bd09-b9fa79af382e"], "id": 3}

response => qSetExpression shouldn't be empty
{"jsonrpc":"2.0","id":3,"result":{"qSetExpression":""}}

call/response as extracted from chrome dev tools (qSetExpression is not empty):
{"delta":true,"handle":1,"method":"GetSetAnalysis","params":["$","ffff1727-97e8-440c-bd09-b9fa79af382e"],"id":78,"jsonrpc":"2.0"}
{"jsonrpc":"2.0","id":78,"delta":true,"result":{"qSetExpression":[{"op":"add","path":"/","value":"<appName={'___a'}>"}]}}

@dvasseur,

I think the key detail is that the Chrome request is using delta mode:

{"delta":true,"handle":1,"method":"GetSetAnalysis", ...}

So the response you see there is not the final qSetExpression string. It is a delta patch:

"qSetExpression":[{"op":"add","path":"/","value":"<appName={'___a'}>"}]

That means the effective value is actually:

<appName={'___a'}>

------

So the first thing I would check is whether your client is handling delta responses correctly.

If you use delta: true, you need to apply the patch operations before reading the value. If you want the plain value directly, test the same call without delta mode and make sure nothing else in your websocket client is forcing delta behavior.

Hope this helps. Please give it a like, mark it as Helpful or Solution if that was the case.

Hi @hugo_andrade

The websocket calls are just "OpenDoc" => "GetBookmarks" => "GetSetAnalysis" so no delta involved.

I've added "delta: True" to the call but same issue, response is empty 😞

Hi @dvasseur ,

I see. 

I think the main issue is the first parameter.

For GetSetAnalysis(qStateName, qBookmarkId), the first argument is the state name. For the default state, Qlik says it should be left empty.

Try 

{"handle":1,"method":"GetSetAnalysis","params":["","ffff1727-97e8-440c-bd09-b9fa79af382e"],"id":3}

$ is the default identifier in set analysis syntax, but in this API call the method expects a state name, and for the default state that should be an empty string.

That's what I found here: 

https://help.qlik.com/en-US/sense-developer/November2025/Subsystems/EngineJSONAPI/Content/service-do...

qStateName

Optional. The name of the state to get set analysis expression for. If left empty, the default state will be retrieved.

String

@hugo_andrade I just tried with an empty first param, same issue 😞
