Hello,
Im getting this error on Nprinting 17 (april 2018) when trying to reload metadata from a connection
30 de Maio de 2018 09:53:41 | Error | Cache generation failed: Error processing request of type Qlik.Reporting.Engine.Messages.Requests.QlikViewDocumentMetadataRequest for sense app b2e35d67-596d-4168-b7b6-27c124f8d18a. ERROR: Object reference not set to an instance of an object.. Check logs for details. |
I also saw this thread Nprinting Error: Object Reference not set to an instance to an object but without success.
I tried to remove one extension that could be the cause, but still getting the same issue.
Where can I see in logs what is the object that Nprinting is looking for?
I cant edit my report because it says? You must generate the cache for the app 'DOP - Excecoes - Hora em Hora' before editing the report template.
Any clue?
Thanks in advance
I dont know exactly what was the cause but the problem was solved after:
- removed the extension
- corrected one variable that was with wrong value
- removed one sheet
Sometimes the nprinting_engine.log offers more detail, search the log in %ProgramData%\NPrinting\Logs in the NPrinting server machine.
and maybe turn the debug mode on. help document provides steps how to do this.
