unsupported-media-type

This operation does not accept that Content-Type.

What it means

detail names the Content-Type that was received and the ones the operation accepts.

What to do

Send JSON as application/json. To validate, send the document as application/xml, or as {"document": "..."} in application/json.

Example

Sent as application/problem+json (RFC 9457). Branch on type, which is stable. Never branch on title or detail, which are prose and may change.
