ACTUAL RESULT:

Failed to fetch basic information about resellers, clients and domains data from source servers
Cause: Failed to execute SQL query on Plesk database: failed to parse JSON returned by SQL script.
Query:
SELECT Subscriptions.id as subscription_id, clients.id, login, pname
FROM clients
LEFT JOIN Subscriptions ON
Subscriptions.object_id = clients.id
AND Subscriptions.object_type = 'client'
WHERE clients.type = 'reseller'
