I meet an error as picture. I opened my Knime as normal. And try to drug a normal node in my under development workflow. Then this error appeared and I failed to add node. I can copy and paste node in my current workflow but I can not drug a node from node repository. Anybody knows how to fix it?
this happens with every dragged node in every workflow? Can you try starting your KNIME with -clean parameter? Navigate to the installation location on the command line and execute ./knime -clean
