I run a workflow in a CRON job. Sometimes I get a warning or an execution failed:
eg WARN KNIME-Worker-10-GET Request 3:824 Node Cannot loop fewer than once
Could there an option in the new UI to look up the node id nr(eg 3:824 with this warning) in a workflow and directly open it?
Hi @Burg,
Thanks for your feature request. I have two related questions: What do you mean with directly open it, the node configuration? If this is a warning, it should be displayed inside the workflow monitor, but I guess this might be not the only warning of this workflow, right?
@schramm When the CRON as automatically run the workflow, I receive an email with all the errors that occurred.
eg part of the email
ERROR KNIME-Worker-3-Excel Reader 3:749 Node Execute failed: Resource deadlock avoided

In the old UI the number of the node was displayed in the workflow so pinpointing and correction was easier. Now you have to open the node to see the number in the top bar of the pop-up window.
If you have multiple occurrences of the the same node in a workflow this takes quit some time to find the right one.
I don’t understand what you mean with the workflow monitor. I was unable to find it
