What it means

A 415 Unsupported Media Type response indicates the request body is in a format the server does not support. This often happens when the Content-Type header does not match what the API expects.

Common causes

• The Content-Type header is missing or incorrect.
• The API expected JSON but received form data, or vice versa.
• An unsupported file type was uploaded.

How to fix it

• Set the correct Content-Type header for the request.
• Check the API documentation for supported media types.
• Convert the file to a supported format if uploading.
