Creation of pdf mail failed: HRESULT E_FAIL returned from a call to a COM component

[Scopes18]

Hi,

the task to mail out a qlikview entity report as pdf attachment failed with:

HRESULT E_FAIL has been returned from a call to a COM component.

It worked before, but on some days it doesn't

Lines from the logfile are below.

Anyone has an idea?

Thanks,

Johan

Open the QVW and check the object used in your entity report to ensure that it is operating normally in the QVW itself.

- does it respond to selections?

- does the object exist any longer or has the object ID changed?

Perform the checks/tests above.

Also check for unsupported items such as

-sheet/document triggers

-Alternate states

-always one selected list box items.

For more on how to workaround unsupported items see https://support-cdn.qlik.com/articles/000026081

Hi,

Thanks for your response.

The weird thing is that 3 out of 4 times it runs successfully, and then a task fails

There are 2 tasks with both a report (rep01 and rep02) from the same qvw, but to a different recipient list. They are planned at the same time. According to the documentation that should be possible to do. 

Now if there is a failure. It's on 1 report. Either rep01 or rep02. It fails immediately and then the other report processes for 6 minutes and then succeeds in generating and distributing.

When both reports succeed: the task takes less then 1 minute. The cpu/ram usage on both servers (Qlikview and nPrinting) is not peaking above 60%.

Can it be the qvw gets blocked sometimes, that is not available for nPrinting? It's quite random.

[Frank_S]

Make sure that (in addition to ensure no unsupported items):
1. the QVW is not being processed by a reload on the QV server during NP metadata reload
2. Do not try to schedule NP publish tasks at the same time as a NP metadata reload
3. If you are sharing the NP service account with any other NP server or even a QV server, this will also cause intermittent failures.
4. Upgrade to the latest version of NPrinting in order to leverage the most recent performance enhancements, bug fixes and advanced logging.

Hi @Scopes18 , @Frank_S ,

Were you able to fix this? I have the same issue with a client and I tried several thinks, but nothing is working

Thanks

Hi @pasgalbarra ,

Please avoid to comment a 3 years old conversation. Many things changed in 3 years and we released many updated versions of Qlik NPrinting. Open a new conversation instead with the label with the correct version of the software you are using, the steps to reproduce the issue, log files or error messages, etc. Include everything that can help use to understand the origin of your issue. Thanks.

Best Regards,

Ruggero
