We created a report in HTML with Charts(as images) and tables from Qlik sense. initially it was working fine and now we getting the below error
Does anyone faced this issue. and using April 2018 Edition
when you go to Qlik Sense and you try to preview this object - how much time does it take to render?
Maybe object is timing out and Image is not generated in Qlik?
Few more questions then...
did you try to recreate a report with just this image? are you sure that id of object creating this image has not change? does NPrinitng service account have an access to this object?
It is also possible that you have updated something in Qlik Sens app but you have not updated all connections and "Nodes" in template
just confirming that you are using native charts - not extensions in Qlik sense. If so you might want to open support ticket with Qlik
again just confirming that Designer version is Also April 2018
other question is. Are you able to create for example excel reports with data or the error apears regardles of the template type?
