exportImg() not working after update to November 2019

[dselgo_eidex]

Hello. I use the Visualization API to render charts in a mashup and I have not been able to get the exportImg method working ever since I upgraded from April 2019 to November 2019. In my mashup I create a qViz object and then call exportImg on it when the user hits a button. This was working fine up until we upgraded Qlik Sense a week ago. I've done some troubleshooting and the problem appears to be in the qlik-module.js file.

I follow the method used in the example here: https://help.qlik.com/en-US/sense-developer/November2019/Subsystems/APIs/Content/Sense_ClientAPIs/Ca...

Whenever I try to use the exportImg() method I receive the following error:

TypeError: Cannot read property 'qInfo' of undefined
    at e (qlik-module.30dee5929df163f57068.js:8)
    at Object.e [as printObject] (qlik-module.30dee5929df163f57068.js:8)

    at s (4.93cf436b595543eeedb5.js:1)

I added a break point where the error was being generated (qlik-module.30dee5929df163f57068.js:formatted:38825) and saw the problem is occurring when some function is trying to get the layout defined in the model of the qViz:

Here is the qVis before calling exportImg():

It appears that the properties of the model are getting mixed up and placed in the id property. I don't believe I am doing anything wrong, but has anyone else experienced this problem with the November 2019 release?

I've seen a similar thing that may have the same underlying cause.  See my post:

https://community.qlik.com/t5/Qlik-Sense-App-Development/Nov-2019-release-right-click-from-mashup-st...

I logged a support request with Qlik and they have verified the problem.  I am currently waiting for an initial response from the team it was assigned to.

As an interim fix, I have rolled back to the Jun-SR1 release as it is the last one that I know worked.

Hi,

Do you have any idea on when it might be fixed? In the meantime we might have to downgrade to June 2019 as well.

Hi,

I don't have any update for now, just that it's being looked at to find the cause of it.

Hi all, 

Short update, the root cause has been found and the bug is being tracked as QB-600. If possible contact support and have them attach your case to this issue.

Thank you for the update on this. I updated our support ticket with that information.

Hopefully the last update.

The issue was fixed in November Patch 3 that was released yesterday.
