Facebook Get Status message from node C# Facebook SDK

I am trying to retrieve a message from a node (my own status message): I am using C# Facebook SDK. My GET request is the following:

status = fb.Get("/v2.2/100006927xxxxxx_1568238173xxxxxx?fields=message")

I tested this in Graph Explorer on the development site and it works.

but in my application I get an "Unsuppported Get Request #100" error.

Is there something new because I think that worked before?
