[ERROR] An error occurred while running subprocess ionic-app-scripts.

php:

<?php


$host = "192.168.xxx.xxx";
$user = "root";
$passwort = "pass";
$dbName = "connectedcar";


$db_connection = mysqli_connect($host,$user,$passwort,$dbName);

if ($db_connection) {

    $utfQuery = "SET NAMES 'utf8'";
    mysqli_query($db_connection, $utfQuery);

    $query = "SELECT wert FROM ultraschall WHERE id = 1";
    
    $result = mysqli_query($db_connection, $query);

    $ult1 = $result->fetch_all();

    echo json_encode($ult1);

    
    
}

else {
    die("Die Verbindung zur Datenbank ist fehlgeschlagen");
}
?>

and the provider:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';



@Injectable()
export class GlobalProvider {

dif1:number;

constructor(public http: HttpClient){}

insertIn() {
    this.http.get("http://192.168.xxx.xxx/test/getUltra1.php").subscribe( data => {
        this.dif1 = JSON.parse(data["body"]);
    })
}

}

when i use the insertIn() function i get this error. if i don´t use it, it works.
