How to Remove error message with Digest Auth in php

I made a API Request with Authentication in php and Code is working and everything good

this is Code PHP:

error_reporting(E_ALL); 
ini_set( 'display_errors','1');

$url = "http://192.168.254.124:80/osc/commands/execute";
$username = "THETAYN10113693";
$password = "10113693";
$Body = json_encode( array( 'name' => 'camera.takePicture' ));
$options = array(
        CURLOPT_URL            => $url,
        CURLOPT_HEADER         => true,
        CURLOPT_VERBOSE        => true,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_SSL_VERIFYPEER => false,    // for https
        CURLOPT_USERPWD        => $username . ":" . $password,
        CURLOPT_HTTPAUTH       => CURLAUTH_DIGEST,
        CURLOPT_POST           => true,
        CURLOPT_HTTPHEADER     => array('Content-Type:application/json'),
        CURLOPT_POSTFIELDS     => $Body
   
);

$ch = curl_init();

curl_setopt_array( $ch, $options );

$raw_response  = curl_exec( $ch );

echo "raw response: " . $raw_response; 

but problem is in response I got 2 messages first is error :

raw response: HTTP/1.1 401 Unauthorized Connection

and Second : code is working good :

text/html HTTP/1.1 200 OK Connection: Keep-Alive X-Content-Type-Options: nosniff Content-Length: 92 Content-Type: application/json; charset=utf-8 {"id":"885","name":"camera.takePicture","progress":{"completion":0.00},"state":"inProgress"}

Full Response:

raw response: HTTP/1.1 401 Unauthorized Connection: Keep-Alive WWW-Authenticate: Digest realm="RICOH THETA Z1", qop="auth", nonce="O5kAeduJSn69042jpxNmGA==", algorithm=MD5 Content-Length: 0 Content-Type: text/html HTTP/1.1 200 OK Connection: Keep-Alive X-Content-Type-Options: nosniff Content-Length: 92 Content-Type: application/json; charset=utf-8 {"id":"885","name":"camera.takePicture","progress":{"completion":0.00},"state":"inProgress"}

I don't want the first message ((error message)) to appear ,what I should doing?

thanks so much
