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
Thank you for your question. I have a few questions as well in order to be able to narrow down the problem: From which version did you upgrade from? Did you add any extensions other than Python? When these messages show, is there a prompt to download the missing extensions? If yes, what happens when you click it?
I updated from the 6 to the 6.1
I did’d istall any other extension
the prompt to install the extension tops to the page before the license agreement (it says that an updated version is already installed).
I’m having this problem with KNIME 3.6.1 on macOS. For no obvious reason the REST nodes and the JSON handling nodes (IO, JSONPath etc) have disappeared. The plug-ins are in there.
This happened to me once before and the only way to fix it was to reinstall KNIME from scratch. I can do that, but it’s not really a solution.
