Apps fails to load when banner is null

[marcovandeveen]

The application doesn't load when the banner is null, while assets.banner config paramter is optional

An config with the following returns "There is an issue loading the application"

{
  "assets": {
    "banner": null
  }
}

The same config with the following succeeds:

{
  "assets": {
    "banner": "https://cdn.jwplayer.com/images/nwthWC1U.png"
  }
}
