soapClient() expects parameter 2 to be array

i have a payment gateway in my site, but when i use it i catch this error:
soapClient() expects parameter 2 to be array string given

i try to change it to nusoap_client but nothing happend and not refer to bank payment page
i try to set variables in token for testing but i got error

with soap Client i catch this error that the transaction info is illigal for bank
any idea??

my code is :

        if ( ! $custom ) {
        $Amount = GFPersian_Payments::amount( $Amount, 'IRR', $form, $entry );
    }
    
    $MID = self::get_merchant();

    $ResNum = time();
    $ResNum = apply_filters( 'gf_banksaman_resNum', apply_filters( 'gf_gateway_resNum', $ResNum, $entry, $form ), $entry, $form );

    $CellNumber   = '';
    $MerchantName = 'MID';
    $FormAction   = 'https://sep.shaparak.ir/Payment.aspx';

    if ( ! empty( $config["meta"]["mobilepg"] ) && $config["meta"]["mobilepg"] == '1' ) {

        $MerchantName = 'TerminalId';
        $FormAction   = 'https://sep.shaparak.ir/MobilePG/MobilePayment';

        $Mobile = GFPersian_Payments::fix_mobile( $Mobile );
        if ( strlen( $Mobile ) > 10 ) {
            $CellNumber = $Mobile;
        }
    }
    try {
            $SoapClient = new soapClient( 'https://sep.shaparak.ir/payments/initpayment.asmx?wsdl', 'wsdl' );
            $Token      = $soapProxy->RequestToken( $MID, $ResNum, $Amount, '0', '0', '0', '0', '0', '0', 'ResNum1',
                'ResNum2', '0', ''
            );
        } catch ( SoapFault $e ) {
            $error = $e->getMessage();
        }
    $payform = '<form name="sendsaman" method="POST" action="' . $FormAction . '">
                <input type="hidden" name="' . $MerchantName . '" value="' . $MID . '"/>
                <input type="hidden" name="Amount" value="' . $Amount . '"/>
                <input type="hidden" name="ResNum" value="' . $ResNum . '"/>

                <input type="hidden" name="CellNumber" value="' . $CellNumber . '"/>
            </form>';
