In 4.7, the node GUID Generator delivered unique id in my tables.
Now that I start working on 5.0, the node generate an error “Execute failed: Java Snippet 5:23:0:64: Cannot invoke “Object.equals(Object)” because “source” is null”.
Any idea (or alternative) to sort this out.
Thanks a lot,
First of all, I’m glad the GUID Generator component has been valuable to you in your projects. I will take a look as soon as I can to see if I can replicate the issue and provide a fix. If you are able to replicate the issue using an example workflow with dummy data, please upload it to hub.knime.com and share the link here which would save me a few minutes.
If you don’t hear back in a few days, feel free to @mention me as a reminder .
Hopefully the video links below are accessible.
I downloaded this sample workflow from @mlauber71 which uses the GUID Generator component and it is working fine for me in KNIME AP 5.0 (MacOS). You might want to consider copying the component from this workflow.
Alternatively, you could copy all of the internals from the component and paste them into your workflow like this:
Hopefully this helps!
