I’m experiencing this problem randomly:
Status: Error: Node “GET Request” not available from extension “KNIME REST Client Extension” (provided by “KNIME GmbH, Konstanz, Germany”; plugin “org.knime.rest” is not installed)
ERROR LoadWorkflowRunnable Status: Error: Node “Excel Reader (XLS)” not available from extension “KNIME Excel Support” (provided by “KNIME AG, Zurich, Switzerland”; plugin “org.knime.ext.poi2” is installed)
THe firlst stime afer updating to 6.1 knime, then i reinstalled knime and after installing python integration the problem reappeared.
I’ don’t know wich is the cause but it’s very annoying since these extensions are two among the one I use more
