Array to string conversion

[Maidomax]

I am using the service like this:

    public function sendIpnValidateResponse()
    {
        $ipn = new PaypalIPNListener();
        $ipn->use_sandbox = config('paypal.mode') == 'sandbox';

        try {
            $verified = $ipn->processIpn();
        } catch (\Exception $e) {
            \Log::error('Problem with IPN validation');
            \Log::error($e->getMessage());
            $verified = false;
            return $verified;
        }

        \Log::debug('IPN Validation response is' . ($verified ? 'VERIFIED' : 'INVALID'));
        \Log::debug('Report:');
        \Log::debug($ipn->getTextReport());

        return $verified;
    }

And I see this in the logs:

[2019-01-30 23:45:00] staging.DEBUG: IPN Validation response isVERIFIED
[2019-01-30 23:45:00] staging.DEBUG: Report:

Seems there is a problem with the getTextReport() method.
