Hello Experts,

When using the Moodle WS core function moodle_course_get_courses according to the documentation:

$res = $mdl_ws_client->__soapCall('moodle_course_get_courses', array(array('ids' => array(1, 2, 3))));

... I get the following error returned:

Error Message: Invalid external api parameter: options (Unexpected keys detected in parameter array.)

The WS documentation for this call reads as follows:

moodle_course_get_courses

Arguments

options - operator OR is used

General structure
Default to "{$a}" //options - operator OR is used
object {

list of (
int //Course id
)}
