Connection Cache Error

Anders_Eriksson — Wed, 04 Jul 2018 09:46:09 GMT

Qlik NPrinting November 2017

Qlik Sense April 2018

Have several connections to the Sense server for Apps in stream Everyone. All but one working?

They use the same Proxy-adress and user, copied Sense app ID from Hub.

Verification is okay and Connection status successful on all NPrinting engines (only one, single server installation).

But for this single application I get Cache status = Error after some seconds running (not immediately when showing Generating).

Have even made a copy of the App and published to stream Everyone under a different name and that works!?

User has access to application in the Hub, no Section Access.

nprinting_webengine.log says "Reload metadata task d2011d9c-9aed-4243-a61d-5d791d15c209 sent to queue" but nothing more.

Nothing in any other log-file and nothing in Windows logs.

What could be the issue?

Don't want to delete and republish the Sense applikation since there are user objects I don't want to loose.

May be this can:

What is the result of running a verification on the Connection details screen?

What do you see under Admin > Task executions & you select the relevant task?

Check the Task name, relevant logs.

Check these:

As I said above verification is okay.
No task, this is the cache build directly when creating the connection.

I have already checked the NPrinting documentation without finding anything relevant.
And as I stated, connections to other Sense applications in the same stream works.
Even a copy of this application published in the same stream under a different name!

Hi Anders,

I wonder on which version of Qlik Sense was this app created? Since the duplicate of the app works i assume it can be something (some legacy) in the qvf file causing an issue.

Wha tyou can do is :

create a duplicate
publish and replace (overwrite) existing app. This will keep your user created sheets and all Id's will be the same. It should not break anything and is definitely worth trying.
try re-generate metadata

cheers

Sorry, already tried to re-publish over the old published version with no success.
The application is published but NPrinting cache generation generates error.

Is it possible that for this particular AppId you have some security rule applied which could prevent it from full required access?

Re: Connection Cache Error

Anders_Eriksson — Thu, 05 Jul 2018 07:31:53 GMT

No special security rule for this app and no section access.
The user used in the NPrinting Connection has no problem accessing the app in Sense Hub.

In such case i would open support ticket with Qlik and let them investigate.

Also keep us posted if you resolve this as it is quite interesting issue...

cheers

Yes I will, first I wanted to ask if someone else had the same experience.
Appreciate your effort.

Hi Anders, did you ever figure this out?

I'm running into the same problem, error when reloading the connection cache on a older app (I'm publishing and replacing the updated app over the new one).

If I publish the exact same app, same stream on its own (without replacing), the cache generation works fine.
