[haietza]

Testing version Kaltura release 4.4.8 2023100901 of the plugins on PHP 8.1 with Moodle 4.3 and get the following errors:

Invalid event functions defined in \mod_kalvidassign\event\assignment_details_viewed

line 275 of /lib/classes/event/base.php: call to debugging()
line 53 of /mod/kalvidassign/view.php: call to core\event\base::create()

Deprecated: Optional parameter $groupfilter declared before required parameter $perpage is implicitly treated as a required parameter in /var/www/asulearn-test.appstate.edu/mod/kalvidassign/renderer.php on line 719

Also the following on the grade submissions page:

line 275 of /lib/classes/event/base.php: call to debugging()

user_picture::fields() is deprecated. Please use the \core_user\fields API instead.

Invalid get_string() identifier: 'grade' or component 'moodle'. Perhaps you are missing $string['grade'] = ''; in lang/en/moodle.php?

The call to get_string is incorrect in renderer.php:369. I needs the component argument; either 'grades' for Moodle core lang pack or 'kalvidassign' for KVA lang pack.

Just want to put a little context to this error. These functions had been deprecated completely in Moodle 4.3 on:

get_legacy_logdata
set_legacy_logdata
get_legacy_eventname
get_legacy_eventdata

See https://github.com/moodle/moodle/blob/v4.3.4/lib/classes/event/base.php#L270-L276

They should be removed from all kaltura's classes.

The "Invalid get_string() identifier: 'grade' or component 'moodle'. Perhaps you are missing $string['grade'] = ''; in lang/en/moodle.php" is fixed by #434.
