Hi,

I try to send email message via moodle api, and I get this strange error:

other event data must be compatible with json encoding

line 770 of /lib/classes/event/base.php: call to debugging()

line 808 of /lib/classes/event/base.php: call to core\event\base->validate_before_trigger()

line 156 of /lib/classes/message/manager.php: call to core\event\base->trigger()

line 104 of /lib/classes/message/manager.php: call to core\message\manager::send_message_to_processors()

line 251 of /lib/messagelib.php: call to core\message\manager::send_message()


I try to invoke the function with:

message_send(($message));
message is an object, containing all the relevant details.

the message is sent, but the error is printed.

anyone knows why?

You can find the string "other event data must be compatible with json encoding" and a reason in the file lib/classes/event/base.php :

 protected final function validate_before_trigger() {
        ...

        if ($CFG->debugdeveloper) {
            ...
            $encoded = json_encode($this->data['other']);
            // The comparison here is not set to strict as whole float numbers will be converted to integers through JSON encoding /
            // decoding and send an unwanted debugging message.
            if ($encoded === false or $this->data['other'] != json_decode($encoded, true)) {
                debugging('other event data must be compatible with json encoding', DEBUG_DEVELOPER);
            }
