After install of NodePit all workflows error - can't open anything

LB_Knime · February 8, 2023, 6:00pm

I just successfully (I think) installed NodePit so I could use the Data Generation nodes.
I can now see the new nodes in the Node Repository.
But when I try to open a workflow, I get an error and can’t even see the workflow. Same happens when trying to create a new workflow.
Error with NEW workflow:

Cannot invoke “org.knime.core.ui.node.workflow.WorkflowManagerUI.getID()” because “this.m_manager” is null

Error with EXISTING workflow:

java.lang.IncompatibleClassChangeError: Found interface org.knime.core.node.workflow.WorkflowContext, but class was expected

Not sure if this is relevant, but I don’t see NodePit as an option when I navigate View > Other… > KNIME Views.
I’ve sent a message to the NodePit feedback link, but not sure what that will lead to.

Here is one snippet from the Error Log:

Pasting our email response here:

Hi there,

the error message suggests a general KNIME issue which is not specific to NodePit.

Yet to clarify:

(1) Which steps exactly did you take to install NodePit?
(2) Did you install any other extensions beside NodePit?
(3) What’s your configuration? (OS, version, extensions, …)

Best,
Philipp

Thanks @qqilihq and sorry for double posting.
I followed the instructions all the way to
“Once added, save and close the preferences window, choose File → Install KNIME Extensions… , choose Work with: -- All Available Sites -- and select NodePit for KNIME for installation.” (Note that my UI was a little different - no “Work with:” text, but I found “NodePit for KNIME”, and went through the wizard without any manual changes.

I did not install any other extensions.

I’m running Windows 10 Pro on a Lenovo laptop.
KNIME 4.6.1
Not sure how to identify any extensions I may have installed in the past.

Problem solved!
Your basic questions helped me to notice that the NodePit install was version 4.7 while my KNIME app version was 4.6. I updated KNIME and all seems well again.
I didn’t see any advice in the installation instructions about compatibility.

Thanks for the help.

That’s great, happy to hear, and thank you especially for posting the solution!

For further NodePit-related questions, we’ll be happy to help - here or via email!
