Error 400 by application/json Post.

[Schlapp7]

hi Guys,

I have the following problem:

I send a Post request to the Griffin.WebServer via the dotNet HttpClient.
The Post request is to be transmitted by a Json.
The content type is application / json.
I get the following answer:

StatusCode: 400, ReasonPhrase: 'Unsupported content-type: application/json',

Why?

I hope you can help me.
