Load section of config file into dictionary in net 5.0 - .net-5

Question

I have to work on an application in net 5.0 not developed by me, that I don't know.
I would like to add a section in the config file and load it into a dictionary.
this is the section in config file:
{
"MyApp": {
"ServiceExceptions": [
{ "Key1": "Value1" },
{ "Key2": "Value2" }
]
}
}
this code load the configuration:
public static IConfiguration GetConfiguration(string name)
{
IConfiguration oConfiguration = null;
string basePath = Path.GetDirectoryName(typeof(SharedHelper).Assembly.Location);
string configPath = Path.Combine(basePath, "Config");
string fileConfig = string.Format("{0}.{1}.json", name, Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"));
oConfiguration = new ConfigurationBuilder()
.SetBasePath(configPath)
.AddJsonFile(fileConfig, optional: false, reloadOnChange: true)
.Build();
return oConfiguration;
}
this is the code to load to bind the dictionary, but myExceptions is null:
_Configuration = GetConfiguration("BD.Authentication.DWA");
Dictionary<string, string> myExceptions = null;
_Configuration.GetSection("MyApp:ServiceExceptions").Bind(myExceptions);
Debug.WriteLine(myExceptions.Count); // throws exception null reference
somewhere are loaded the data, but i dont know how to pull out

Just move the config file in:
{
"MyApp": {
"ServiceExceptions":
{ "Key1": "Value1" },
{ "Key2": "Value2" }
}
}
and retrive the values:
var serviceTypeExceptions = _Configuration.GetSection("MyApp:ServiceExceptions").Get<Dictionary<string, string>>();
