Node-Red seems to have problems randomly - how to debug?

Hi!

Randomly, my node-red is not doing the things, what it should do. In about 80-90% of the scenes the rules are working like a charm and as expected. But sometimes, the rules are just not correctly set. And i do not know why.

Im wondering for a while why the following notice occurs whenever i press the button “deploy”, but as said, in the major of the situations the rules are correctly set, meaning the following hint is not really usefull for me.

Can anyone help me where i find something like a logfile or how to debug node-red?
