Error: Unable to add nodes to project

Hi everyone,
I’ve got a following problem. I’ve installed KNIME today on Linux and when i try to add a node in my project, the program crashes with that error:

Have anyone any idea how to fix it?

Hi @maciej_wisnia,

Thanks for contacting us!

Kindly be informed that we need more information to investigate this issue.

We would like to clarify some points:

  • does this occur with any node?
  • what Linux do you have?

Also, we would like to ask for log files as far as they may contain more information (knime.log and the eclipse “.log” file).

Both log files are located in the workspace directory:

  • KNIME logs: <knime-workspace>/.metadata/knime/knime.log
  • the eclipse .log: <knime-workspace>/.metadata/.log

Looking forward to your reply!

Best regards,
Dzhanhir
