• The Java classes compile correctly outside Talend using javac.
• The PDFBox jar used is pdfbox-app-3.0.7.jar.
• The custom jar does contain the expected .class files.
• The main issue seems to be class and dependency visibility at job compile time, not necessarily at runtime.

Hi All, How to apply colors here by each measure in qliksense  14.231.5 version.

there is no option to each measure here.
Please help me on this?

We are facing an issue in Qlik Sense Enterprise on Windows (May 2025 Patch 17) where the Data Connections panel keeps spinning for 3 minutes after opening the data load editor. When it loads webconnectors and webstorage connectors are missing in the create new connection window .Below error is displayed in web console

connector: error executing connector method getConnectionInfo, retrying: QvWebConnectorPackage.exe undefined
connector: error executing connector method getConnectionInfo, retrying: QvWebStorageProviderConnectorPackage.exe undefined

In the custom connector logs C:\ProgramData\Qlik\Custom Data\QvWebConnectorPackage\Log  below is displayed 

09 Jun 2026 11:44:16,488 [1] - ERROR - PipeName=command_1437881e13dd5ca493b8ad2efc37aecd044f4d40 Source=QWC ReloadId=NA TenantId=NA UserIdType=NA UserId=NA EngineSessionId=NA AppId=NA RequestGuid=NA ConnectorId=NA Sender=Program Message=Unhandled exception.

The same error is also observed for QvWebStorageProviderConnectorPackage

Has anyone encountered this issue before?

Admin has force updated Service account password recently.
All Qlik services were restarted with the new password.

Problem Description

We are experiencing an issue where QlikSense apps created using the "Duplicate" feature return incomplete or empty metadata when accessed through the QlikSense Engine Service (port 4747) via WebSocket connections.

How We Access QlikSense

We connect to QlikSense Enterprise using:

• Connection Method: WebSocket (wss://)
• Port: 4747 (Qlik Sense Engine Service)
• Protocol: HTTPS/WebSocket
• Purpose: Extracting app metadata including load scripts, variables, sheets, and object definitions

Specific Issues Observed

1. Empty Variables Metadata

When retrieving app variables from duplicated apps:

Expected Structure:

{
  "qItems": [
    {
      "qId": "variable-id",
      "qName": "VariableName",
      "qDefinition": "expression"
    }
  ]
}

Actual Response from Duplicated Apps:

{}

Impact: Cannot retrieve any variable definitions from the app, even though variables are visible in the QlikSense Hub UI.

2. Empty Load Script

When retrieving the load script from duplicated apps:

Expected: The complete load script with data loading logic, transformations, and connection strings.

Actual Response from Duplicated Apps:

{}

Impact: Without the load script, we cannot understand the app's data sources, transformations, or data flow logic.

3. Missing Object Metadata

When retrieving sheets, dimensions, measures, and master objects, we observe:

• Empty or missing JSON responses
• Incomplete object definitions
• Missing visualization metadata

Even though these objects are visible and functional in the QlikSense Hub.

Environment

• QlikSense Enterprise on Windows (QSEoW) — November 2025, version 14.254.6
• Accessing via QMC / browser only

More Details : 

When using the built-in Duplicate function on a QlikSense app, certain copies (in my case the 10th duplicate, named TestApp2Copy(10)) return completely empty metadata when accessed via the QlikSense API.

Specifically, all extracted data files are empty or missing:

• variables.json contains only {} — no qItems array
• loadScript.json contains only {}
• sheets/, dimensions/, measures/, masterObjects/, stories/, bookmarks/ folders are all empty

The original app (TestApp2Copy) and all other copies (TestApp2Copy(1) through TestApp2Copy(9), and copies named without parentheses like TestApp2Copy1, TestApp2Copy2, etc.) return full, valid metadata correctly. And If I renamed the App name to TestApp2Copy10  then that will work with the new name (OR) even if I created another AppTestApp2Copy10 then Both TestApp2Copy(10) and TestApp2Copy10 will works

Steps to Reproduce

1. Export any working App  eg: TestApp2Copy.qvf
2. Import it as Duplicate   First Try to name TestApp2Copy(1) , TestApp2Copy(2), ....etc
3. The extracted apps will get fails using the API
4. Try to rename it to TestApp2Copy1, TestApp2Copy2  it will work, else create another apps TestApp2Copy1, TestApp2Copy2..... Then Both TestApp2CopyN and (TestApp2Copy(N) will work.

Observed Behavior

The API returns {} for GetVariables and GetScript for the affected app, even though the app appears fully functional in the QlikSense Hub UI (sheets are visible, data loads correctly).

Renaming the app (removing the (N) suffix) and re-accessing via API returns valid data, suggesting the issue is specific to how the server handles metadata retrieval for apps with parenthesized suffixes at certain indices.

Expected Behavior

The API should return full metadata (variables, load script, sheets, etc.) for all duplicated apps regardless of the copy number or naming convention.

Questions

1. Is there a known issue with the QlikSense Duplicate function returning incomplete metadata for apps at certain copy indices?
2. Is there a server-side fix or workaround other than exporting to .qvf and re-importing?
3. Does this correlate with any known behavior related to the (N) naming pattern used by the Duplicate function?

Hello,

We have a situation where a QVF apparently got corrupted; attempting to open the app results in an "Unsupported file format" error message. We are also unable to export the app or publish over it. 

Is our only option to delete the app from the QMC and publish a new instance even though doing so is going to delete any community sheets associated with the app? 

Is there anything we can do to prevent the loss of the community sheets?

What if, instead of deleting the app thru the QMC, I manually delete the corrupt QVF from the file system and replace it with an new instance with the same name/UUID as the deleted instance? 

Thanks for any help,

Steven

This Friday, I'll be joining @Ouadie for a live look at Choose Your Champion 2026, an interactive World Cup prediction experience powered by Qlik. Join us on LinkedIn for Live Stream Friday at 9am EST.

We'll explore how Qlik Cloud Analytics, Qlik Predict, Qlik Answers, and APIs were combined to create a fan experience featuring predictive brackets, win probabilities, conversational AI, tournament history, and interactive analytics.

Before we go live, we'd love to hear from the Qlik Community:

• What aspect of the application are you most interested in seeing?
• What questions do you have about the machine learning, predictive modeling, or AI behind the experience?
• What would you like us to cover during the livestream—technical details, model development, user experience design, or something else?

Drop your questions and ideas below, and we'll try to address as many as we can during the session. We hope to see you there!

Hi everyone,

I've been working on improving the structure and performance of my Qlik load scripts and front-end apps, and I want to make sure I'm following the most current best practices... not just what was recommended 3 or 4 years ago.

I'm looking for resources that cover topics like:

• Load script structure and organization
• Data model optimization (star schema, avoiding synthetic keys, QVD layers)
• Performance tuning (set analysis efficiency, AutoNumber, incremental loads)
• Naming conventions and maintainability

My question to the community: What are the most current and reliable sources you use to guide your development decisions? For example:

• Official Qlik help docs or whitepapers
• Community blogs or specific contributors you follow
• YouTube channels or webinars
• Internal standards your team has developed

Any links, authors, or resources you'd recommend would be greatly appreciated. Thanks in advance!

I know Ideation is a thing. I use it. But sometimes you just want to share ideas in an informal way.

So, here's my personal Wishlist. No ticket numbers, no upvotes required. Just ideas:

i am using an automation to fetch the receipt table data from my sheet for current receipt month. when i am applying the filter in the sheet using the same field and choosing 2026-06 it is showing around 54 rows but when same thing i am trying to filter in the automation using a variable in the sheet called current month which fetches the current month year . then i am using the same variable in my automation filter. but i am getting the error as error:Object data can't be bigger than 100.000 cells.
