Hello, i would know if it's possible to combine 2 dataStore in one other dataStore. Thanks by advance

it's cool but when i try it i have this error : Warning: Invalid argument supplied for foreach() in C:\wamp64\www\koolreport\koolreport\core\src\core\DataStore.php on line 1289 i send you the code :

$this
        ->src('assurance')
        ->query($queryStr)
        ->pipe(new \koolreport\processes\ColumnMeta([
            /* "date" => [
                "type" => "datetime",
                "format" => "d-m-Y"
            ],
            "montant" => [
                "type" => "number",
                "decimals" => 2,
                "decimalPoint" => ".",
                "thousandSeparator" => " "
            ], */
        ]))
        ->pipe($this->dataStore('assuranceDS'));

        $this
        ->src('assurance')
        ->query($queryStr2)
        ->pipe($this->dataStore('assuranceDS2'));

        $this->new_store = $new_store =  $this->dataStore('assuranceDS')->leftJoin($this->dataStore('assuranceDS2'),array("id_test"=>"id_toto"));
