Error 415, also known as "Unsupported Media Type," is an HTTP status code that indicates that the server refuses to accept the request because the media type or representation of the resource is not supported. In other words, the server is unable to handle the format of the data being sent in the request.
This error typically occurs when the Content-Type header of the request is not recognized or supported by the server. The Content-Type header specifies the media type of the data being sent, such as JSON, XML, or form data.
To resolve this issue, you can check the Content-Type header in your request and ensure that it is set correctly and supported by the server. Make sure to use a media type that the server is expecting and can process properly.
If you are developing an API, it is essential to provide proper documentation specifying the supported media types for each endpoint. This will help clients send requests with the appropriate Content-Type header and avoid encountering the 415 error.
