Can't save the workflow

Hello ppeng,

Could you please give a little more context to this problem so that we can understand it better? It would really help if you can share a sample workflow and mention with which node/functionality you are facing this issue.

A similar issue related to snappy compression was reported before. I hope the below information on the previous forum thread helps you to solve your issue.

  • try opening a fresh WF and copy/paste the whole thing and try saving that without internal data storage
  • try changing the compression to (GZIP or NONE) by passing the value to the parameter in your knime.ini file - requires restart
