unsupported-media-type

Description

The Content-Type header in the request specifies a media type that the endpoint does not support. Most JSON endpoints require application/json; endpoint-specific media types are listed in the API reference.

Response Example

Code
{
  "type": "https://docs.kordiam.app/docs/errors/unsupported-media-type",
  "title": "Unsupported Media Type",
  "status": 415,
  "detail": "Content-Type 'text/plain' is not supported",
  "instance": "/api/v2/elements",
  "traceId": "abc-123-def",
  "supportedMediaTypes": ["application/json"]
}

Common Causes

• Missing the Content-Type header on a request that includes a body
• Using Content-Type: text/plain instead of application/json
• Using a media type that is not documented for the endpoint

How to Fix

Set the Content-Type header to the media type documented for the endpoint. For JSON endpoints:

Code
Content-Type: application/json
