I have a KNIME workflow with an Excel Reader node to read in the data. However, I can’t execute the node properly and there seems to be an unusual error which says “java.lang.ArrayIndexOutOfBoundsException: -1”
Now I’m unable to fix this issue by rerunning KNIME, resetting the whole workflow, or rebooting my computer. The preview keeps on getting interrupted when I open configuration so I’ve disabled it. Please look at the attached picture for more details on the configuration of the node. Any suggestions on what might be causing this and how I can fix it?
