Can't open knwf files

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
