Can i not use the object(Table) from connection A and Connection B (connection A and Connection B from same qlik App)
in the same template?
When i do this iam getting an error : object reference not set to an instance
Let's focus on one thing at a time.
Further, your clarification re: 2 connections made with the same source document/Sense app inside the same NP app is not supported for your version of NPrinting.
Connection rules for Qlik Sense apps
The following rules apply to connections to Qlik Sense apps:
In fact this support only began in Feb. 2021 version of NPrinting. I have tested and it works as designed in Feb.2021. You can view the fix in the Feb. 2021 release notes - attached. OP-9606
So upgrading as @Ruggero_Piccoli suggested is the solution.
If you have a separate issue to this, please start a separate thread.
Yes, you can create two, or more, connections to the same Qlik Sense app inside a single Qlik NPrinting app. Be sure that all connection caches are correctly updated. If you refresh the cache you must close and re-open the designer.
when I am pulling the object(Table X) from only conn A or only conn B i am able to preview it
but when i am pulling from both the connections(same object Table X) Nprinting is throwing an error:
Object reference not set to an instance.
Can you please suggest a solution on this?
By searching your error message I found the following articles:
Please check if one of the solutions suggested on them works also for you.
I tried but still the issue persists.
One object at once is perfectly fine but when i put one from connection A and one from Connection B then the error occurs.
if possible can you be able to try to see if same error occurs.
Can you please suggest any other solution?
In my installation it works without issues.
Can you share some screenshots of the template or export the template? A qvf with scrambled data? I want to try to reproduce your issue.
Be also sure that you are not using unsupported objetcs https://help.qlik.com/en-US/nprinting/February2021/Content/NPrinting/ReportsDevelopment/Qlik-objects...
If you cannot share them here, I suggest you to open a support ticket with everything we need to reproduce the issue and a link to this conversation.
I am simply creating an app using below table.

I have Nprinting April 2020 and Nprinting Designer April 2019 Will this cause any issue?
Using the wrong version of NPrinting Designer may have an adverse affect on your NPrinting reports not withstanding possible corruption of those reports therein.
Please upgrade your NP designer so that it matches your NPrinting server. (in your case NP designer April 2020)
Unfortunately your report may already be damaged. If needed redo your report and try again.
