"Exception - Call to a member function get() on bool" Error Message
Closed this issue · 2 comments
We are running version 2023020107 of the Attendance module under Moodle 4.1.5.
Unfortunately, the QR code generation feature is no longer working. When you allow students to take their own attendance and choose to have a QR code generated, clicking on the icon to display the code opens a new page in Moodle with the following error message: "Exception - Call to a member function get() on bool." I get the same error message when I set a password for student recording of attendance and click on the "key" icon to view the password. I go to this page - https://[moodle url]/mod/attendance/password.php?session=36258, but I see only that "Exception - Call to a member function get() on bool" error message.
I turned debugging on and go the following stack trace along with the error:
Exception - Call to a member function get() on bool
Debug info:
Error code: generalexceptionmessage

The QR code feature was working fine when we were using Moodle 3.11 (and that version of the plugin), but it is not working now.

It turns out that the problem was with a second plugin that was installed on our server, although I'm not sure how it got there. There was a "Metagroup sync" plugin (AKA "local_metagroup") that was several years old. Once we removed that plugin, the QR code functionality worked fine, without causing any errors.
Thanks for the update - great to hear you tracked the issue down!
