What is the meaning of the absence of a Form Data header when inspecting POST requests in the developer tools?

edit

The absence of a Form Data header when inspecting POST requests in the developer tools may indicate that the request body is not being sent in the traditional HTML form data format. Instead, it may be using JSON, XML, or another format to send the data. The absence of the Form Data header does not necessarily mean that there is an error in the request or that the request is invalid.
