CORS on Qlik Sense Desktop

mamltdv — Sat, 16 Nov 2024 02:15:26 GMT

Hi all,

I am new to Qlik and I am testing the Desktop version to call the API from a web page.
I have created a simple example, but I get the following error:

Access to XMLHttpRequest at 'http://localhost:4848/api/v1/csrf-token' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I have read that you can modify this in the server configuration, but I cannot find how to do it in the Desktop version.

Thanks in advance,
Miguel Ángel

Hello @mamltdv

Can you provide a sample code showing which API you are trying to call and steps to replicate the issue ?

Runnning below command from the Run is fixed the issue:

chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security

CORS- It allows you to make requests from one website to another website in the browser, which is normally prohibited by another browser policy. As this is security-related. there are no specific settings on qlik sense desktop to avoid this error.

Alternatively, you can create a chrome browser shortcut with web security disabled.

Launch chrome exe with the parameter which disables the web security

Example:

chrome.exe --user-data-dir="C://tmpChromeSession" --disable-web-security
