Hi,
I can’t open one workflow as below alert. How to fix it?
java.lang.NullPointerException: Cannot invoke “java.util.List.iterator()” because the return value of “org.knime.core.node.workflow.SingleNodeContainerPersistor.getFlowObjects()” is null

Hello @eddy0620 ,

What version of Java do you have installed (java -version) and what version of KNIME AP are you using?

Hi，NDekay
Java version:

KNIME AP:

Hello,

Thank you for the additional information. I realized belatedly that the Java version would be irrelevant, as AP 4.6.3 uses Java17 internally anyway.

However, the issue you reported has been registered as defect AP-19701 and is slated for fix in AP 4.7.0.

Lastly, we recommend that you remove the provided workflow from the forum, as it appears to contain some proprietary or sensitive information.

Thank you,
Nickolaus
