Hi @gabrielfs2 ,
Welcome to the community!
Well, some tips for you… The community can help you if you print your flow and bring us a demo of the data, workflow… Can you upload something to us?
For your question, knime have “try and catch node” to make this solution. IF the first path have a problem, you can use a second path to substitute the first one.
An example from this case: Try Catch within a Loop - #2 by Thyme
“Try” to start the process for monitorion, “Catch” to register the operation and decide IF was sucess or error situaltion and take a decision, pass or change the flow using the second condition.
I hope that it can help you,
BR,
Denis
