HTTP Status Code 415

A status code 415, also known as "Unsupported Media Type", is an error message that pops up when a server rejects a request because it doesn't understand the format of the data being sent. This data is often called the payload, and it typically comes from the user's browser.

There are a couple of reasons why this error might occur:

• The first is a mismatch between the format of the data and the "Content-Type" label attached to it. For instance, if you're uploading an image but the label says it's a text file, the server will be confused.
• Another reason is that the server might simply not be programmed to handle the specific format of the data you're trying to send.
