Hi my manager_config.json looks like this :

{
  "loadLocales": true,
  "markers": {
  "TruckAsset": {
    "attributeName": "can_rpm",
    "showLabel": true,
    "showUnits": true,
    "colours": {
      "type": "range",
      "ranges": [
              {
                "min": 0,
                "colour": "00FF00"
              },
              {
                "min": 800,
                "colour": "FFFF00"
              },
              {
                "min": 1500,
                "colour": "FF0000"
              }
            ]
    }
  },
  "LightAsset": {
    "attributeName": "onOff",
    "showLabel": false,
    "showUnits": false,
    "colours": {
      "type": "boolean",
      "true": "6ae8fc",
      "false": "016170"
    }
  },
  "realms": {
    "default": {
      "appTitle": "GreenVision : Saarthi GreenTech",
      "styles": ":host > * {--or-app-color2: 
#F9F9F9; --or-app-color3: 
#22211f; --or-app-color4: 
#0c4da2; --or-app-color5: 
#CCCCCC;}",
      "logo": "/images/logo.png",
      "logoMobile": "/images/logo-mobile.png",
      "favicon": "/images/favicon.ico",
      "language": "en"
    }
  }
}

TruckAsset is my custom asset that i have created but the name is exactly “TruckAsset” in the file that I have created.

I have used the fleet-management repo
But my map markers remain blue
