Problem with OnDemand-Feature

lprill1 — Mon, 14 Jun 2021 11:54:52 GMT

Dear Qlik Community,

Since last Tuesday, we have been getting the following error message in Chrome and Microsoft Edge when using the OnDemand feature for NPrinting.

An error occurred:
{"code":403, "message": "User has no rights to access the resource"}.

We had this error once in the past, but were able to resolve it with the help of the following post:
https://community.qlik.com/t5/Qlik-NPrinting-Discussions/Nprinting-Ondemand-not-working-on-Chrome/td-p/1682939

The error occurred suddenly without us changing anything in the application. Strangely enough, the OnDemnad function works in Internet Explorer.

Support has already been informed, but maybe someone from the community has had the same experience recently.

Already many thanks and best regards
Lennart

Hi,

Could you, please, try to replicate the problem with the Browser dev tool active and generate an HAR file? There should be more info there:

Could you, please, also double check that you can reach the NPrinting console from the Sense Server?

@lprill1

Check the following article. it has the necessary information to construct your user custom or existing NP security roles as needed or to add On Demand report access.

https://community.qlik.com/t5/Knowledge-Base/Troubleshooting-QlikView-On-Demand-with-NPrinting-19-and/ta-p/1759095

The error is usually due to a permissions issue.

Can you double check if the NP role(s) with On Demand Access are assigned to that user?

Perhaps Role permissions or Role access for the user in question were changed recently...it's worth looking into.

But make sure to go through the article above from end to end to ensure that On Demand is configured as needed.

Hi guys

thanks for your quick replies.

@Frank_S :
That's very unlikely as we really haven't changed anything in the environment. Also, the problem occurs with all users. Nevertheless, I checked again - everything should be configured correctly in the console.
And it does work in the Internet Explorer browser - what is strange in my opinion.

@Andrea_Bertazzo :
Enclosed I have created a HAR file for you.
Also I can reach the NPrinting console from the reload-, development- and access-server.

Thank you very much again and best regards
Lennart

Hi,

Are you sure you are using February 2021 and not February 2020? Could you check please? That is because we solved a similar issue in February 2020 SR1. From the Release Notes:

Chrome SameSite cookie
Jira issue ID: OP-9144
Starting from February 2020, Google Chrome 80 manages the SameSite cookie differently. Qlik NPrinting supports this new configuration on both HTTP and HTTPS connections. On-Demand for Qlik Sense and QlikView will continue to work.

If it affects all users, you did not change nothing and it affects Chrome and Edge (both use Chromium engine) I suspect it still is the SameSite cookie problem you linked in the first message.

Best Regards,

Ruggero

Hi @Ruggero_Piccoli ,

thank you for your reply. I just checked again and yes, we have installed the February 2021 version.

What I noticed is that if you search for "samesite" under Chrome://flags, there are only two, instead of three, (see screenshot) results. Has something changed here with a newer Chrome version?

Many thanks and best regards
