Can't use JSON event formatting with appsettings.json

I wanted to log in json files with .Net Core 2.2. However, it writes my logs in a non json format

Here is my appsettings.json file

  "Serilog": {
    "MinimumLevel": "Fatal",
    "WriteTo": [
      {
        "Name": "Async",
        "Args": {
          "configure": [
            {
              "Name": "File",
              "Args": {
                "path": "..\\Logs\\log.json",
                "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact",
                "rollingInterval": "Day",
                "retainedFileCountLimit": 5, 
                "fileSizeLimitBytes": 1073741824, 
                "rollOnFileSizeLimit": true, 
                "outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level}] {Message}{NewLine}{Exception}{NewLine}"
              }
            }
          ]
        }
      }
    ],
    "Properties": {
      "Application": "Common feature in WebApi demo"
    }
  },

I even tried to delete the outputTemplate field but it always writes as 2019-06-05 10:42:32.952 +01:00 [Fatal] {My data}

Hi Pedro,

The problem here is that outputTemplate and formatter are mutually-exclusive: only one or the other should be specified. Currently, when the configuration is ambiguous, the library will just choose one itself, which is outputTemplate in this case.

Removing the outputTemplate option will get this working.

HTH!

Hi @PedroS11 ,

Just checked with your config, it works. If you still hit the issue, try to update to the latest versions of the packages. If it doesn’t help, please re-open issue. Thanks
