Error Connecting to database

[techkimchhay]

I am trying to connect to database but get an error like this

`C:\wamp64\www\smb-report\vendor\geekcom\phpjasper-laravel\src\PHPJasper.php
/**
* @param bool $user
* @return mixed
* @throws Exception\InvalidCommandExecutable
* @throws Exception\InvalidResourceDirectory
* @throws Exception\ErrorCommandExecutable
*/
public function execute($user = false)
{
$this->validateExecute();
$this->addUserToCommand($user);

    $output = [];
    $returnVar = 0;

    chdir($this->pathExecutable);
    exec($this->command, $output, $returnVar);
    if ($returnVar !== 0) {
        //throw new \PHPJasper\Exception\ErrorCommandExecutable();
        throw new \Exception("{$output[0]}", 1);
    }

    return $output;
}

/**
 * @return string
 */
public function output()
{
    return $this->command;
}

/**
 * @param $user
 */
protected function addUserToCommand($user)
{
    if ($user && !$this->windows) {
        $this->command = 'su -u ' . $user . " -c \"" . $this->command . "\"";

Arguments
"usage: jasperstarter process [-h] -f [ ...] [-o ] [-w]"`

and here is my config

` public function generate()
{
//$input = DIR . '/vendor/geekcom/phpjasper/examples/hello_world.jasper';
$input = base_path('/vendor/geekcom/phpjasper-laravel/examples/Database.jasper');
$output = base_path('/vendor/geekcom/phpjasper-laravel/examples');

    $options = [
        'format' => ['pdf'],
        'locale' => 'en',
        'db_connection' => [
            'driver' => 'mysql',
            'username' => 'root',
            'password' => '',
            'host' => '127.0.0.1',
            'database' => 'smb',
            'port' => '3306'
        ]
    ];

    $jasper = new PHPJasper;

    $jasper->process(
        $input,
        $output,
        $options
    )->execute();
    return view('welcome');
}`

could you please help to tell what's went wrong?

Good afternoon, I have the same or similar mistake
usage: jasperstarter process [-h] -f <fmt> [<fmt> ...] [-o <output>] [-w]
Help, please

[jorgeescobar]

with this code the error does not come out anymore, but the fields in the report come out as NULL
$jasper->process( $input, $output, array('pdf', 'rtf'), array('php_version' => phpversion()), array( 'driver' => 'mysql', 'username' => 'root' 'password' => '', 'host' => 'localhost', 'database' => 'ksoftdb', 'port' => '3306',) )->execute();
help please...
