“Unable to load workflow ‘/WHM/Whales’: Unable to load workflow, it was created with a future version of KNIME (4.1.3.v202005121100). You are running 4.1.2.v202003050920.”
So I did a server upgrade to 4.10.3 and that went without any trouble, then I did a executor update with the update-rmi.sh script
Now I still have the “Unable to load workflow ‘/WHM/Whales’: Unable to load workflow, it was created with a future version of KNIME (4.1.3.v202005121100). You are running 4.1.2.v202003050920.” error message on the new flow BUT now none of the old flow works either I get “Load error” with this message
" org/knime/core/node/workflow/FromFileNodeContainerPersistor$PersistorWithPortIndex"
Glad to hear you could solve this on your own! To give you some background on what most likely happened: there is a good chance that an old (pre-upgrade) executor process was still running. When you start KNIME Server, it will detect this process and try to use it as executor. Which obviously was prevented due to the version mismatch.
If something like this happens, it is enough to just kill all leftover executor processes, no need to restart the whole machine
This will not be enough in this case, since the old executor process was not started by the current Tomcat process. Therefore, it can’t be shutdown by just using the scripts.
