Why does the error message "Invalid request. Passed parameters: Array()" appear when clicking on Save?

The error message "Invalid request. Passed parameters: Array()" appears when clicking on Save because the parameters being passed to the server are not in the correct format. This could be due to incorrect data formatting or missing parameters in the request. To solve this issue, ensure that the parameters being passed are properly formatted and match the expected format on the server side. 

// Example of properly formatting parameters before sending the request
$data = [
    'param1' => 'value1',
    'param2' => 'value2'
];

// Convert data array to query string
$queryString = http_build_query($data);

// Send request with properly formatted parameters
$response = file_get_contents('http://example.com/api/save?' . $queryString);

// Handle response from server
if ($response === false) {
    echo 'Error: Unable to save data.';
} else {
    echo 'Data saved successfully!';
}
