Node-Red Error Bombing!

Hi guys,

I haven’t been using Node-Red for very long so please excuse me if this question is very simplistic for you. Despite my limited knowledge I have built a few (sub-) flows that work so far. However, when I try to use the debug function, I get a bombardment of error messages. These seem to be functionally meaningless, since the flows work just fine. Can anyone tell me how to stop these errors from appearing?

If you click on the node name it will show you the node that is causing the error (eg. click on “Status Esstisch Jalousie” next to “node:”). There is possibly something wrong with the configuration of these nodes.

Probably deleted or renamed entities
