Hi - this is now the third time this specific question has been asked (and answered) in the last couple of days. Is that a coincidence or are you asking again and again hoping for a different answer?
Those messages are coming from a node. The node id begins with 1a47...
- in the top right corner of the debug messages.
- Have you searched for the node id to find it (starts
1a47
in the top right corner of the debug messages)? - Have you opened the Configuration Nodes sidebar and checked you have no nodes hiding in there?
- Have you restarted Node-RED since deleting everything just to make sure it wasn't a badly implemented node that hasn't tidied up after you deleted it.
