The APM dotnet core agent doesn't read configuration from the appsettings.Release.json

appsettings.Release.json:
	{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Elastic.Apm": "Debug",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
      
    }
  },
  "ElasticApm": {
    "ServerUrl": "http://10.10.10.10:8600",
    "SecretToken": "xxxxxxxx",
    "ServiceName": "ServiceCatalog", 
    "Environment": "ServiceCatalog_prod"
    }
	}

and I am passing the configuration in the Startup.cs to app.UseAllElasticApm method as below :

using Elastic.Apm.NetCoreAll;

namespace ServiceCatalog
{
    public class Startup
    {
        public IConfiguration Configuration { get; }
        
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseAllElasticApm(Configuration);

        }
    }
}

you can find the log below :

Hi, @bassem_abdalftah.

We don't control the loading and binding of the configuration values and can only access those provided via the IConfiguration instance passed into UseAllElasticApm. The Microsoft extension libraries (Microsoft.Extensions.Configuration, etc.) handle the loading of the values from the various configuration sources.

It doesn't look like this release-specific file is being loaded/used. Are you 100% certain that the app is running under the Release environment? At this point, I'd recommend double-checking your application environment and configuration first.

For example, if you add another key to the appsettings.Release.json file and attempt to access it from IConfiguration in your code, does it resolve the value from the appsettings.Release.json file? I suspect it won't.

Hello Steve

after I investigate more in my configuration, I found a typo from my side was causing the error sorry and thanks for your time :smiley:
