lastColor API call fails

[TheRealBenForce]

I'm on v2.2.3

I can set a color:

http://localhost:8934/blink1/fadeToRGB?rgb=%23FF11FF&time=2.7

{
  "blink1Serials": [
    "20004AE9"
  ],
  "lastColor": "#ff11ff",
  "lastTime": 2.7,
  "lastLedn": 0,
  "cmd": "fadeToRGB"
}

When I try to retrieve last color:

http://localhost:8934/blink1/lastColor

Cannot GET /blink1/lastColor

I have read in issue #316 the API changed to retrieve last color using fadeToRGB endpoint by itself, but it is not accurate, color shows as #000000

http://localhost:8934/blink1/fadeToRGB

{
  "blink1Serials": [
    "20004AE9"
  ],
  "lastColor": "#000000",
  "lastTime": 0.1,
  "lastLedn": 0,
  "cmd": "fadeToRGB",
  "status": "bad hex color specified undefined"
}
