What it means

A 406 Not Acceptable response means the server cannot return content in any of the formats the client said it would accept, based on the Accept, Accept-Language, or Accept-Encoding headers in the request.

Common causes

• The client requested a content type the server does not support.
• The client requested a language the server cannot provide.

How to fix it

• Adjust the Accept headers to include formats the server supports.
• Check the API documentation for available content types.
