notice with failed request

Hi,

I am getting a notice with a seeminlgy failed request:

Notice: Undefined offset: 0 in C:\DEV\sites\tools-si\vendor\plesk\api-php-lib\src\Api\Client.php on line 163

dumping the $xml variable yields the following:
object(PleskX\Api\XmlResponse)[475]
public '@attributes' =>
array (size=1)
'version' => string '1.6.9.0' (length=7)
public 'site' =>
object(PleskX\Api\XmlResponse)[241]
public 'get' =>
object(PleskX\Api\XmlResponse)[474]

there is no 'result' attribute under 'get'

Here's my request:




PARENT_NAME


<gen_info />



<disk_usage />

with PARENT_NAME being the name of a webspace as speciefied by the guide: https://docs.plesk.com/en-US/onyx/api-rpc/about-xml-api/reference/managing-sites-domains/available-filters.66544/

plesk version for this server is 17.0

running with "plesk/api-php-lib": "1.0.4" in composer.json

It would be awesome for all these info to be available with php and not though requests

Start at src/Api/Client.php line 163 and reproduce the request against the Plesk 17.0 API using the XML shown in the report. Compare the response without a result attribute with the Plesk XML API documentation; the issue is resolved when this response is handled without an undefined-offset notice and the expected behavior is verified.
