400 Bad request when viewing embedded single sheet in iframe inside our application

[Vasyl]

Hello, we are using Qlik Sense charts inside our application by showing them in iframes. 

We are taking links from Qlik side by opening Qlik project and taking link inside "embed sheet" window.

When viewing this embedded sheets on application side  we see "400 Bad Request" error but it appears randomly, sometimes sheets are opened properly and sometimes we see "400 Bad Request". 

We are using tickets system for authentication and Window type of entering the credentials.

Any advices?

Since upgrading to feb2020 (from nov2018) we are experiencing the same issue.

I noticed that it can be related to sessions timeout. When Qlik user session timeouts then this embedded app still tries to use old Qlik ticket and result is 400. 

Note that this is only assumption. Any help will be very helpful.

Hi!

Have you found a resolution to this?  We are having the same issue with a Qlik sense February 2020, as well.

Qlik Support reckons this is related to this article: https://support.qlik.com/articles/000098524 (which has a workaround).

Otherwise, the fix is apparently scheduled for April 2020 SR1, and June 2020.
