change user password with curl command

[greeniptv2016 0]

hi friends thanks for your help
I use this command to change passwprd user but it doesn't work here is the command:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'http://localhost:8096/emby/Users/IDUSER/Password?api_key=APIKEY');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"CurrentPw\":\"\",\"NewPw\":\"1234\"}");

$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: MediaBrowser Client=\"testingembyclient\"';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);
 

if I send this command via ssh terminal:

curl -X POST "http://217.61.22.21:8096/emby/Users/3c09dd7980f24ce7b05755ab2e9df617/Password?api_key=ba48738200f746c68c4b76d2a602e8df" -H "accept: */*" -H "Content-Type: application/json" -d "{\"CurrentPw\":\"\",\"NewPw\":\"cuck\"}"

i have this error:

Object reference not set to an instance of an object

I add that I can create users without problems
thank you
