Hi

The D* aliases are only defined if you choose a NodeMCU or Wemos board. They are not defined for the 'Generic ESP8285 Module' that you obviously chose. You can work around this by either changing all the occurances of the D*-labels, or by changing to another board or by defining aliases by yourself:

Are you using ThingPulse hardware? Then you should use a Wemos D1 board
