Hi,

I'm trying to get all calendar events for today thru the XML RPC API in Odoo V12 using PHP. 

$calendarEventIds = $this->models->execute_kw(DB, UID, PASSWORD, 'calendar.event', 'search', array(array('start_date', '=', '2019-09-03')));

Somehow if I remove the date filter, I do receive the whole list. So the date filter does not seems to work. Is there something wrong with my syntax?

Stacktrace:
