"status": 415, "error": "Unsupported Media Type",

This error message typically occurs when the server is unable to process the media type of the request made by the client. It indicates that the format or structure of the data sent by the client is not supported by the server.

Some common reasons for this error include:

- The server expects a specific media type such as JSON, XML, or plain text, but the client sends a different type.
- The client sends malformed or incomplete data that the server cannot parse or understand.
- The server is misconfigured and does not recognize the media type specified in the request.

To resolve this error, the client should ensure that they are sending the correct media type and format that the server expects. They can also try specifying the media type explicitly in the request headers. If the issue persists, the server administrator may need to review the server configuration and update it accordingly.
