Nprinting Designer giving HTTP call error sending request in Sep 2019 release

PoojaPrasad — Wed, 23 Oct 2019 16:04:28 GMT

Hello Experts,

We have upgraded the environment with September release and have re-installed Nprinting designer. But when we are trying to edit template of any of the old reports, we are getting below error while Nprinting Designer 2019 opens:

HTTP call error sending request

https://<>, method GET. Http status code InternalServerError (500)

I have checked the below link.

https://support.qlik.com/articles/000046868

The workaround did not work.

Also, checked

https://community.qlik.com/t5/Qlik-NPrinting-Discussions/NPrinting-Feb-2018-Error-Message/td-p/12192

I am not sure which admin password is being refereed in the resolution of the post.

Any help for this error is appreciated.

Thanks in advance,

Version: Nprinting 19.29.3.0

We're getting the same error. I'm interested in the solution.

Hello @PoojaPrasad @robert_bond

I see that you have stated you both upgraded your environments to NPrinting Sept. 2019.

But please note that you must also manually upgrade the NPrinting Desktop to the same version as the NPrinting server on wherever you are intending to design NPrinting reports. Upgrading the NP server will not auto update the NP designers.

If you can verify that you indeed did also upgrade each individual NP designer using the NP designer install program, I would suggest the following.

1. Fully uninstall the NP designer and restart the computer. Please also restart the NPrinting server.

2. Perform a new download of the NP designer from the Qlik Downloads site

3. Right click on the installation file and click the 'General' tab and click 'Unblock' if you see the button on the lower right corner of the general tab.

4. Right click on the NP designer installer and select 'run as administrator' from the right click context menu.

5. Test again.

If these steps do not solve the issue, please start a support request so we can begin to look into this as soon as possible for both of you.

Kind regards.

Hi @Frank_S ,

I followed your instructions and the error message remains (see pic below) when I try to run Nprinting Designer.

Here's our environment:

Qlik NPrinting Server: September 2019 Version: 19.29.3.0

Qlik Nprinting Designer: 19.29.3

Hi @robert_bond

If you like I can look at your NPrinting logs here in the community if you wish.

However if you prefer to keep your NPrinting logging information private, I would suggest starting a support request as mentioned.

If you choose the latter, please share this community discussion in the support case which you submit.

Thank you...fs

Hello Frank,

Thank you for responding with probable solution. Same like Robert, the above steps did not help resolve the issue. So, have asked the Qlik Support team to help look into the issue. Will update if we get the solution.

Note: We have not yet upgraded our production instance and we are able to open Nprinting designer Sep 2019 version with previous version.

Frank_S — Wed, 23 Oct 2019 18:53:28 GMT

Thank you @PoojaPrasad

Doing so will help our team to further investigate the issue. Please also return here if you don't mind to share the solution as @robert_bond is doing.

Kind regards...

Hi @Frank_S . I tried the solutions Alan mentioned. Since he's on PTO today, is there someone else who can work with me today?

Re: Nprinting Designer giving HTTP call error sending request in Sep 2019 release

PoojaPrasad — Fri, 25 Oct 2019 14:40:49 GMT

Hello Robert,

Is it possible to share the solution? I have not yet heard back from Qlik Support team on this issue. It will help if you could share the solution/workaround you got from them.

Thanks,

robert_bond — Fri, 25 Oct 2019 14:56:38 GMT

Hi @PoojaPrasad , below is the solution that Alan suggested. I tried and it didn't work for us. Can you try and reply w/ results?

===========================================

HI Robert, Franks has made some suggestion:

Troubleshooting the 500 Internal Server Error from Client Side

The 500 Internal Server Error generally is caused by the server (NP server in this case)

1) Restart the browser after clearing the cache and deleting the cookies

2) Try a different browser to access the NPrinting Web console before attempting to open and edit a report.

Hi @PoojaPrasad

Robert's Qlik support case owner is out today and we are also experiencing a high volume of cases today as well.

I was contacted yesterday by the tech working his case and started assisting with that one. In any case I will also share with you any suggestions or findings during the investigation.

One thing you need to check is to make sure that you are not using your NP service account to run the following services. You must allow the defaults to apply as shown in the image below...these must not be changed.

I will come back here with any new news as well.

In them mean time make sure to send your NPrinting Logs to your support case along with the following information. Do NOT submit this private company information here as the community as this a public forum:

• Your Qlik NPrinting 16 Digit Product License key.
• The version of NPrinting that you have installed in this format. QV 12.2 SRx, 18.x.x SRx etc
• Are you upgrading or installing and configuring NPrinting for the first time?
• If QlikView, is the version of QlikView Desktop installed on the NP server/engine the same version as the QV Server? Which QlikView version is in use? What is the Operating System of the QV server? Win2008 R2? 2012 R2? Other?
• If Qlik Sense, which version of Qlik Sense is in use? What is the Qlik Sense operating system? Win2008 R2? 2012 R2?
• Can you describe specific steps to help us reproduce this behavior?
• Send us a video or screen grab that demonstrates the behavior.
• When did you first notice the problem? Has this worked before?
• Has there been a recent change in the environment, performed an Upgrade or Migration on your system
• Please provide NPrinting 17+ Log Files - C:\ProgramData\NPrinting\Logs
( https://support.qlik.com/articles/000026186 )
• Windows event viewer logs
( https://support.qlik.com/articles/000007495 )
• Technical details of the host server/machine QV, QS and NP machine
( https://support.qlik.com/articles/000004240 )

Hi @robert_bond , tried both the workarounds. Neither of them worked. Still the same error when opening Nprinting designer.

Let me know if you get any other workaround/solution.

@PoojaPrasad

Private message your Qlik Support case number and I will ensure that the software defect ID gets added to it.

Thank you.

Re: Nprinting Designer giving HTTP call error sending request in Sep 2019 release

PoojaPrasad — Fri, 25 Oct 2019 21:36:39 GMT

Thank you Frank for the update. I will inform my team to revert back to Nprinting April 2019 release for the time being so that our development does not go on halt.

Kindly keep us updated with latest updates on the issue.

Thank you.

Hi @PoojaPrasad

Can you wait until Monday at least or possibly tuesday?

I am concerned that rolling back 'might' cause result in the same issue.

If you are rolling back using VM server images, then that will be fine.

Kind regards...

Hi @PoojaPrasad ,

Just spoke w/ Qlik R&D. The answer is that the problem is caused by an old version of the NPrinting repository database. You need to upgrade the NPrinting database to the latest version. There is a tool in Nprinting which allows you to do that.

@Frank_S , could Alan post the steps to upgrade here?

Thanks,

Robert

Frank_S — Tue, 29 Oct 2019 19:59:08 GMT

@robert_bond @PoojaPrasad

According to R&D.

You have both likely restored an older version of an NPrinting database overtop of an upgraded NPrinting repository.

Once you upgrade using the upgrade/installer, it is NOT necessary to perform a restore.

Upon execution of the NP server installation file, this action processes/updates all NPrinting tables. No further action is required. It is not necessary to perform a restore after the upgrade completes. All tables and modified/added/updated during the installation/upgrade process.

For details see:

Article containing resolution: https://support.qlik.com/articles/000086996
Reference article: Installing/Upgrading NPrinting: https://support.qlik.com/articles/000050323
Reference article: Back up and restore NPrinting: https://support.qlik.com/articles/000032251

In any case, the steps taken with you by R&D today will not be necessary going forward. It was a one time action.

To prevent this in the future, do not restore an older NP database repository database over an upgraded NPrinting server.

Note the upgrade process also makes and stores pre-and post NP databases in the following location as well.

C:\ProgramData\NPrinting

I'm pleased to hear the issue is resolved for you @robert_bond

@PoojaPrasad Since you are rolling back as previously mentioned, the next time you upgrade please check the points above and avoid an NP database restore 'after' performing an upgrade as doing so is not necessary and will break NPrinting. Also your rollback is actually a good idea. It will allow you to perform a clean upgrade on your next attempt.

Kind regards...
