Hi all,
When trying to publish a datasource to tableau server via “send to tableau server”, I am getting the following error message and I’m a bit lost as what to do.

ERROR Send to Tableau Server 0:10 Execute failed: Failed to start a new Hyper instance.
Context: 0x86a93465

CAUSED BY:

Can anyone help?

Hi @steffi ,

What version of KNIME are you currently running?

We had an issue before in older versions where the hyper.log file was being written to a location that the AP User account did not normally have access to, which caused an error for the write permissions. It has since been changed in 4.3.0 + to write the hyper.log file to a temporary folder instead of what I see here of: C:\Windows\System32.

You can also test fixing the issue by giving the user kuaq6n access to write C:\Windows\System32\ but this may not be advised or allowed on your system.

Thanks,
Zack

Hi Zack @ztrubow ,
Thanks for the hint. That was it. I reinstalled KNIME and it worked fine afterwards :slight_smile:
Thx
Steffi
