How to set environment variables for complex configuration parameters in AWS lambda using asp.net core 3.1 serverless?

In my asp.net core 3.1 web API launchsettings.json I have a environment variable named "AdminstratorConfig:AdminstratorPassword": "myPasswordValue"

Now in my code I also have a class named AppSettings defined like this:

public class AppSettings
{
    public AdminstratorConfiguration AdminstratorConfig { get; set; }
}

public class AdminstratorConfiguration
{
    public string AdminstratorPassword { get; set; }
}

When running in my local I can bind the environment variable into my AppSettings instance using something like this in the Startup

public class Startup
{

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

    public void ConfigureServices(IServiceCollection services)
    {
        var appSettings = new AppSettings();
        Configuration.Bind(appSettings);
        // Here appSettings.AdminstratorConfig.AdminstratorPassword contains value 'myPasswordValue' 
    }
}

I cal also load the same from my appsettings.json if I have my configuration defined as

{
   "AdminstratorConfig": 
    {
       "AdminstratorPassword": "myPasswordValue"
    }
}

However after deploying my application as AWS serverless lambda I tried to set the same environment variable in Lambda configuration section but it doesn't allow special characters here ' : '

Is there a way we can set and load these complex environment variables in AWS Lambda similar to my local? if not what are the possible alternate approaches?

You can use __ (double underscore) instead of : (colon), so the environment variable in lambda would be AdministratorConfig__AdministratorPassword as the key and your myPasswordValue as the value.

See the documentation.
