For POST resource :

you need to add uri_paths like this :

uri_paths = {
"create" = "/student-api"
}

In your post method, you are trying to access the POST data via the $data parameter. However, to retrieve data from the POST request body, you need to use the Request object. Here's how you can modify your code to access the POST data

<?php
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Exception\HttpException;

// ...

/**
* Responds to POST requests.
*
* @param \Symfony\Component\HttpFoundation\Request $request
* The request object.
*
* @return \Drupal\rest\ModifiedResourceResponse
* The HTTP response object.
*
* @throws \Symfony\Component\HttpKernel\Exception\HttpException
* Throws exception if needed.
*/
public function post(Request $request) {
// Retrieve POST data from the request body.
$data = json_decode($request->getContent(), TRUE);

if ($data === null) {
throw new HttpException(400, 'Invalid JSON data in the request body');
}

// Now, you can access and work with the $data array.

// Example: Print the data to the log.
\Drupal::logger('your_module')->notice('Received POST data: ' . print_r($data, TRUE));

// Implement your custom logic here.

// Return a response.
return new ModifiedResourceResponse('Response data');
}
