ASP.NET Core Odata Service Post not working - asp.net-core

Question

I implemented a ODATA Service in my ASP.NET Core application. The GET function is working fine, but I have some problems with the POST function.
If I excecute a POST the programm is excecuting the right method but I don't receive any data.
Is there anything missing in my code?
Controller:
[EnableCors]
[ODataRoutePrefix("documents")]
public class DocumentController : ODataController
{
[ODataRoute]
[EnableQuery]
public Document PushDocument([FromBody]Document doc)
{
System.Diagnostics.Debug.WriteLine("DomentID: " + doc.Id);
System.Diagnostics.Debug.WriteLine("Dokument: " + doc.RawDocument);
return doc;
}
}

Since you use [FromBody], you need to send data as Content-Type: application/json,in postman：
Startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.AddOData();
services.AddMvc(options =>
{
options.EnableEndpointRouting = false;
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseMvc(b =>
{
b.MapODataServiceRoute("odata", "odata", GetEdmModel());
});
}
private static IEdmModel GetEdmModel()
{
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Document>("Documents");
builder.EntitySet<Press>("Presses");
return builder.GetEdmModel();
}
