Generate report fail using Nprinting

Wed, 25 Sep 2019 18:40:54 GMT

I created a report using Npriting and Qlik Sense.

The report with third part extension (Qwidget).

My Qlik Sense version is 2017 June 11.11

My Nprinting version 17.4.

When preview or run the report task. Error as following.

Failed report generation for report c9b2ca9d-37c2-411b-8de6-e08e16e07262 user f2f358ed-617c-404f-a569-b7f6b1c43b5c exception Qlik.Reporting.Reports.Tree.Exceptions.FailedReportException: Report generation failed.

Hi,

did you read this topic?

https://help.qlik.com/en-US/nprinting/June2017/Content/MultiDocument/UsingSenseThirdPartyExtensions/Using-Sense-third-pa…

There are requirements around extensions which have to be fulfiled before you can use them with NPrinitng. If they are not met then we cannot do anything.

----------------------------------------------------------------------------------------------------------------------------------------------

Creating a report using Qlik Sense third-party extensions

As of Qlik NPrinting June 2017, you can use Qlik Sense third-party extensions inside Qlik NPrinting reports as images, tables, and levels.

See: Visualization extensions

Requirements

As of the Qlik Sense June 2017 release, all objects that have been added to a sheet can be used as images. Qlik NPrintingdoes not distinguish between native visualizations and extensions. However, for a third-party extension to render correctly, the JavaScript implementation of the extension needs to fulfill certain requirements. In particular, the extension must implement the "finished rendering" notification.

A third-party extension can be used as a table if:

The object contains exactly one hypercube.
The hypercube is either straight or stacked.

A third-party extension can be used as a level if:

The properties of the object contain exactly one hypercube.
The hypercube is either straight or stacked.
The hypercube has at least one dimension.
The hypercube contains no calculated or grouped dimensions.

Qlik NPrinting does not support the exporting or printing of visualization extensions that use:

External resources.
Internal and undocumented JavaScript modules or APIs.

Setting up a "finished rendering" notification

To export your third-party extension as an image, you must use the paint method to inform Qlik NPrinting that the extension has finished rendering. Otherwise, you could have blank or partially rendered images.

// ..., paint : function() { return qlik.Promise.resolve(); } // ...

See: Enabling export of your visualization extension

----------------------------------------------------------------------------------------------------------------------------------------------

btw. Does your NPrinting report work if you remove extension object from its template?

cheers

Lech

Thanks for your information.

But what I can do for inform Qlik NPrinting that the extension has finished using following.

// ..., paint : function() { return qlik.Promise.resolve(); } // ...

looks like your extension is using external resources:Remote code could not be executed, error: The operation was canceled

So you know it is extension - why do you want to use extension in NPrinting?

can't it be replaced with something else, like formula, variable or embeded object?

I need to use it like HTML table.

Make the page can be customized by using css and HTML.

So you mean nothing I can do.

Unless change the report to using the standardize one?

What NPrinting template are you using? HTML?
