Content Negotiation Problem re JSON-LD

Currently, we have the following returned for an "application/ld+json" document content-type request

curl -IH "Accept: application/ld+json" https://metahari.solid.community/profile/card
HTTP/1.1 200 OK

Where the content-type is incorrect i.e., it should be "application/ld+json" .

Comienza reproduciendo la solicitud curl documentada contra el endpoint de la tarjeta de perfil y compara el Content-Type devuelto con el tipo solicitado application/ld+json. Rastrea el manejo de la negociación de contenido del servidor desde ese endpoint; el trabajo estará terminado cuando la respuesta identifique el documento como application/ld+json para esta solicitud y el comportamiento esté cubierto por una prueba adecuada.
