HTTP 415 Unsupported Media Type

In short: The data format of the request (Content-Type) is not supported by the server.

In more detail: The server expects JSON, for example, but receives a form or plain text. The Content-Type header does not match what the interface understands.

In Depth

When it occurs

• API call without Content-Type: application/json.
• An uploaded file has a type that is not allowed.

What you can do

1. Check the Content-Type header and set it to match the body.
2. As a user: upload an allowed file type.
