Can't open knwf files

KNIME Analytics Platform
1

Hi everyone,

I noticed that I can’t open knwf files. If I download a workflow from the Forum as knwf or if I export one of my self-build workflows as knwf, I cannot open the file. When I double click, nothing happens. When I drag&drop the knwf file into the KNIME window, nothing happens. Right click > “open with knime.exe”, nothing happens.

Except for that, I can use KNIME AP normally.

But I get the following error message when I want to pull workflows from the Hub into KNIME:

Error Message:

Unable to download workflow: The entity is not backed by an input stream, entity class is : java.io.InputStream

For your information:

  • Version: KNIME Analytics Platform 5.3.1
  • I downloaded “KNIME Analytics Platform for Windows (zip archive)”
  • Windows 10 Enterprise 64 Bit
  • I’m based in China and use KNIME on a laptop without VPN
  • I don’t have admin rights for the laptop
  • I can install KNIME extensions

Thanks a lot for any help!

Best,
Eren

Have you tried open it from inside knime? Maybe you can provide a fresh log file in debug mode?

@mlauber71 Thanks for you reply! And sorry for getting back to you so late. I was on a small vacation :slight_smile:

After deleting and re-downloading the installed (zip) version of KNIME, opening downloaded workflows suddenly works. Don’t know why, but the problem seems to be solved.

Unable to download workflow: The entity is not backed by an input stream, entity class is : java.io.InputStream

Would you be any chance know the reason for the above error message though? The one I get when I try to to pull workflows from the Hub into KNIME.

Best,
Eren
