Hi,
while trying to modify a workflow which I call through Cotnainer Input, all of a sudden I was not able to continue to modify it. The workflow state was reset, I pasted a few nodes, reconnected the flow variables and wanted to delete the “loose end”.
Then the console got spammed. As follows the log of the worklfow containing:
2025-12-24 08:30:12,050 : ERROR : main : : KNIMEApplicationWorkbenchAdvisor : : : Uncaught exception in event loop
java.lang.IllegalArgumentException: Node ID "5:1708" not contained in workflow, nor it's the workflow itself (ID of this workflow is "5")

I cannot fully replicate it but when it is triggered, I have to close the workflow. After it being saved and reopened, the “loose ends” are gone.
