Getting empty success with Geonames

[ux-engineer]

Hi,

I'm having trouble debugging what went wrong with this Geonames API query, as I'm getting only an empty response object?

Here's output on psy shell (using Laravel's 'artisan tinker' -tool):

>>> $zip = new PragmaRX\ZipCode\ZipCode;
=> PragmaRX\ZipCode\ZipCode {#693
     +"finder": PragmaRX\ZipCode\Support\Finder {#694
       +"timer": PragmaRX\Support\Timer {#696},
       +"result": PragmaRX\ZipCode\Support\Result {#697},
     },
   }
>>> $zip->setCountry('FI');
=> null
>>> $zip->setPreferredWebService('Geonames');
=> null
>>> $zip->setQueryParameter('geonames_username', 'xxxxxxx');
=> null
>>> $res = $zip->find('07420');
=> PragmaRX\ZipCode\Support\Result {#715}
>>> print_r($res->toArray());
Array
(
    [success] =>
)
