The 415 Unsupported Media Type error is one of the most frustrating errors that website owners encounter. 


It can take hours to diagnose and fix, costing you valuable time, money, and reputation. 


This post will help you understand what causes the 415 Unsupported Media Type error and how to fix it so you can get back to focusing on your website's content!

Can Error Codes Hurt My Website?

Yes, error codes can have a negative effect on your website. 


For example, 404  and 503 errors can frustrate visitors who are trying to navigate through your site but find that certain pages do not exist or cannot be accessed. 


Visitors may leave your site in frustration and never return because of these types of errors. The most important step to take to avoid this type of error is to ensure that your site is well maintained. 


What Is a 415 Unsupported Media Type Error?

The 415 Unsupported Media Type error code indicates that the request entity has a media type that the server or resource does not support. The response code may still be returned if the contents of the request body were not supported by the server. For example, a server might support specific JSON bodies, but the payload contents didn't validate, perhaps because it was missing a required property.


For example, the client uploads an image that was not in one of the formats (e.g., JPEG, PNG), or a video that is not in an accepted format (e.g., MPEG). The best way to fix it is to remove the image or video and upload a file in one of those formats.

Is It a Server-Side or a Client-Side Error?

The 415 Unsupported Media Type status code is a client-side error. It belongs to the HTTP response status codes in the 4xx category, also called client errors. 


The 4xx category contains 20+ HTTP status codes, including:



If you come across a 4xx error, it means that something that is happening on the client-side is the issue. 


4xx status codes differ from 5xx status codes. The main difference is that while 4xx status codes are considered client-side errors, the 5xx status codes are server-side errors. When a 5xx status code appears on your site, that indicates that something's wrong with the server-side of things.


What's the Difference Between a 422 Unprocessable Entity and 415 Unsupported Media Type error?

The description in the standards for 422 is slightly contradicting the one for 415. The 422 error is generated when a client requests an XML document that the server can't process, and 415 refers to an unsupported media type.

How Do I Fix a 415 Unsupported Media Type?

Fixing a 415 error can be time-consuming for the client as it indicates the issue is in what the client is sending that the web server can't process. In other words, if you come across a 415 error, it means that you have to fix the error yourself.

  • Make sure that you are sending the right Content-Type header value.

  • Confirm that the server can process the value defined in the Content-Type header.

  • Check the Accept header to see what the server can process.

Summary
