Service worker execution blocked when using qlik-embed with qlik enterprise on Windows

andreadl_deepcube — Fri, 15 Nov 2024 13:11:45 GMT

Hello i'm trying to embed qlik apps in my react app.
The version of Qlik in use is Qlik Sense May 2024 Patch 5.
I want to use a virtual proxy with ticket authentication.

The js assets loads after being redirected to internal_windows_authentication/?target_id=...

The problem is that the browser blocks the execution of service worker with this error:
Uncaught (in promise) SecurityError: Failed to register a ServiceWorker for scope ('https://{sense_host}/qlik-embed/') with script ('https://{sense_host}/qlik-embed/static-assets-auth-service-worker.js'): The script resource is behind a redirect, which is disallowed.

I noticed that even if i specify data-login-uri to a specific virtual proxy in the script it seems that the proxy in use is Central Proxy (Default), the cookie session name and the access control response header applied belongs to the central and not to the one defined in data-login-uri

<script

crossorigin="anonymous"

type="application/javascript"

src="https://cdn.jsdelivr.net/npm/@qlik/embed-web-components@1/dist/index.min.js"

data-host="{sense_host}"

data-login-uri="https://{sens_host}/msvil"

data-cross-site-cookies="true"

></script>

What i'm doing wrong ?

Hey @andreadl_deepcube I reproduced your issue and seems to be a bug on both docs and code.

I've tried to define the VP into data-host prop and VP is now used by qlik-embed. This could be the bug on docs, but I'm going to check this internally and raised a doc modification request.

Now, qlik-embed starts to load resources using your VP but it is blocking on requesting /resources/autogenerated/product-info.json, which is not an authenticated requests. Seems that cookie for your VP is not used here. This is the code bug.

Please try to set your VP in data-host prop, and if you are able to reproduce product-info.json error, open a support case. I'm going to raise this internally as well.

Hi @alex_colombo,
thank you and sorry for this late response.

I was solving the cookie error that also caused the various redirects to get the ticket via internal_windows_authentication.

Now the correct cookie is set and the assets are loaded correctly with the VP defined in the data-host prop (i removed completely the data-login-uri prop).

However I still have the service worker registration error. I think the server does a redirect because when the static-assets-auth-service-worker.js file is requested the cookie is not sent (even with data-login-uri prop).
I assume this happens because the service worker registration is done inside an iframe.

Seems that cookie is not sent in any case. Which authentication type you are using into you Virtual Prxy? Could you please share you Qlik Virtual proxy configuration?

Hi alex,
we're using ticket authentication.
I've attached a video of the configuration (the allowed host is anonymized)

I've tried to reproduce the issue but looking at my browser developer tool I'm not seeing that call to service worker js file. Could you please share your Qlik embed config and html tab where you are pointing to a Qlik viz?

Hi alex,
i've attached the html file and screenshots.
In order to see the iframe's requests on chrome's network tab you need to enable chrome://flags/#strict-origin-isolation

Hi! I'm trying to set up a mashup (I'm using JWT with QSEOW) and I'm having the same issue.

@andreadl_deepcube were you able to solve the issue?

Thanks in advance.

Hi @andreadl_deepcube

Sorry to bother you again with this but...still no solution from Qlik?

Thanks.

Yes, the customer support said that this a known issue, qlik-embed doesn't work with non-default virtual proxies.
It works only with Central Proxy (default).
I ended up using an iframe that works with non-default virtual proxies, i hope this will work in the future so i will update my codebase, but i don't really believe it.

I'm having the same issue and it seems that is caused by the connection to the service worker that is trying to reach the files without adding the virtual proxy to the url getting an http 400 as response.
