Error [ERR_HTTP_HEADERS_SENT]

[romanstech]

node works excellent except errors below. It doesn't break a functionality but I see these errors in node-red-logs each time I change something in cronjob window. I mean window with drop-down description. These errors are not critical but I prefer to inform you.

[Steve-Mcl]

thanks for the info

I'm not certain where exactly you are seeing these & I'm not sure how they can be related.

could you provide more info? e.g. nodejs version, using https? self cert? via the internet or all localhost?

Perhaps you could also paste a screenshot into the reply?
