WebSocket Error... the device cannot stream THIS resource


#1

Upon opening my dashboard, for a short time a popup appears briefly:

WebSocket Error
ESP8266: the device cannot stream this resource. Maybe the resource name is not defined.

The missing resource is however not named, so one has to guess what it could be…
Would’nt it be better to improve this error message by naming the culprit?
