City4CFD validates configuration when "lod" key is missing.

[amorfinv]

Hello,

I noticed that City4CFD validates the configuration file when the "lod" key is missing. However, it then fails right after with a vague error message. The configuration I am using is as follows:

{
  "point_clouds" :
  {
    "ground": "pointcloud/ground.txt"
  },
  "polygons" : [
    {
      "type": "Building",
      "path": "polygons/buildings.geojson",
      "unique_id": "fid",
      "height_attribute": "b3_h_max"
    },
    {
      "type": "SurfaceLayer",
      "path": "polygons/vegetation.geojson"
    },
    {
      "type":       "SurfaceLayer",
      "path":       "polygons/water.geojson"
    }
  ],

  "point_of_interest": [93898,436173],
  "influence_region":   null,
  "domain_bnd":         null,
  "top_height":         300,

  "bnd_type_bpg":      "Round",
  "bpg_blockage_ratio": false,
  "buffer_region":      20,
  "reconstruct_boundaries": true,

  "terrain_thinning": 10,
  "smooth_terrain":   {
    "iterations": 1,
    "max_pts": 100000
  },
  "building_percentile": 90,

  "edge_max_len": 5,

  "output_file_name":  "Mesh",
  "output_format":     "obj",
  "output_separately":  true,

  "output_log": true,
  "log_file": "logFile.log"
}

This config gives the following error:

👋 @amorfinv. Thank you for reporting. I can recreate the issue, it is a bug in the config file JSON schema.
