I’m executing a Workflow on the KNIME-Server via WebPortal. The first File Reader Node (More then 8 Mill. lines) works fine, but the second File Reader Node (23 lines) gets a NullPointerException.
On my local KNIME installation everything works fine and so it was on the Server. But after I changed a value in a Partitioning Node (testing with less data) and reupload, the Workflow failes due to the NullPointerException at the File Reader Node.
E: After a new reupload, no error accurred. Is the NullPointer just a random error?!
