Invalid course module ID error when saving attendance or taking quiz

Invalid course module ID error when saving attendance or taking quiz

In our install of Moodle we get "Invalid course module ID" error when trying to save attendance for a class.

Starting in the attendance module for a specific course:
http://classes.wrfr.com/mod/attendance/manage.php?id=724

I click on a specific session and get to this page:
http://classes.wrfr.com/mod/attendance/take.php?id=724&sessionid=11&grouptype=0
... with list of students in it.

Regardless of whether I check any students or not, I scroll to bottom and click "Save" and get Invalid course module ID error on this page:
http://classes.wrfr.com/mod/attendance/take.php

If I have changed any of the students' attendance information (for example, clicking "P") that information is saved correctly, even though the next page shows an error.

6 weeks or so ago I went through large upgrade path from 1.9.x to 3.6.1. Today I upgraded successfully to 3.6.2. I turned on debugging and here's what I got:

------------------------------------------------------------------------------------------------------------  

At top of screen I get this debugging dump:

Then the actual error dump is:

------------------------------------------------------------------------------------------------------------


Students also get the same error when taking a quiz. If I log in as administrator then login as a student and take a quiz, after I save the quiz and submit it (ending up on this page: http://classes.wrfr.com/mod/quiz/processattempt.php) I get the same error Invalid course module ID.

Seems related. Any ideas?

Thanks in advance,

Have you found a fixing to this problem already? 

We have the same version of moodle and the same problem. Problem comes out in one course quizzes and also in user management if we want to remove someone. Interesting is that the ID error doesn't come with every user. We upgraded from 3.4 to 3.6.2.

Heidi, wish I could help, but don't really have a solution. Our problem was intermittent on quiz taking, but was going on every time we tried to take attendance.

And then, it wasn't. Nothing explicit I did on the setup side, nothing explicit that the administrator who's actually using Moodle to run classes did, it just hasn't been happening.

I can't really see how this has anything to do with it, but are you sure your cron jobs are running properly? Other than upgrading from 3.6.? (can't remember what previous version we were on) to 3.6.2 the only other major change I made was getting the cron jobs running again (I'd moved directories when I did my big upgrade from 1.9.x to 3.6.x, hadn't updated my cron path)... maybe that's something to look into?

We have cron jobs running but maybe I should check it today. Our debugging gives exactly same rows than yours, except the last three or four rows.

Hi, can you tell please if the cron job was a problem? We still didn't fix our problem too and we can't find any solution.

And it happened again when we copy the assignment from one course to another.


Thank you

The same problem on the same version of Moodle, several quizzes have the same problem


And the error is the same as your except few last lines of error but quite similar actually.


Did you have fix this problem, start to happen this yesterday so we still didn't get to the solution of the problem.

Sorry, no solution yet.

Frustratingly for us, right now we do not have ANY way of generating this error consistently, it's an irregular glitch so right now having very hard time reproducing it.

Appears to be happening in our quiz area when it does happen, not necessarily to students but when it does happen it's sounds like (I'm just the IT-ish guy here) it's happening to the course administrator when he's grading quizzes.

Not any fixing solution here either.  

I imported a new version of the problematic course and it solved the quiz saving problem. But not the problem in user management. Error comes irregularly here too. One failed quiz saving was fixed by itself (maybe because of cron?) but nothing else.

Hi!

We have the same problem after upgrade from 3.3 to 3.6.1. Some quizzes are working without problems, some works only for local account but not for the other forms of authentication like saml. In php_log there are same errors:

PHP Notice:  Undefined offset: 27330 in ../moodle/lib/grade/grade_item.php on line 2498

PHP Notice:  Trying to get property of non-object in ../moodle/lib/grade/grade_item.php on line 2499

Database transaction aborted automatically in ../moodle/mod/quiz/processattempt.php

Default exception handler: Debug: SELECT id,course FROM {course_modules} WHERE id IS NULL [array egg] Error code: errorprocessingresponses

* line 2240 of /mod/quiz/attemptlib.php: moodle_exception thrown

* line 89 of /mod/quiz/processattempt.php: call to quiz_attempt->process_attempt()

Andy, no fix for us yet. It would be great if you submitted this as a bug report, I have NOT done that because I can't reproduce it every time (that's one of the big challenges with this one, seems most people are getting it intermittently). If you have a reproducible spot this happens that would be a great candidate for a bug report, please post here if you do submit one so we can all track it as well.

I have open issue on tracker: https://tracker.moodle.org/browse/MDL-64808 but no response yet.

In my experience, we receive bug during copying quizzes. Sometimes when quiz is copied using duplicate icon on the same course, and sometimes when we import from another course.

Hi Ivica

Tim has kindly linked the 2 trackers together as it seems its related, so hopefully this can be resolved..

Today this ID error came in our another moodle environment (updated to version 3.6.2 yesterday). Both moodle have one course which is updated by importing new material to the old course and deleted the old materials and quizzes. I think this is the common maker in this problem. Is it possible that the problem occurs with users who has studied the material of old version too and it is no longer available?

Hi!

Today we find out that using hide/show maybe is a clue for solving problem. In one course we have noticed that when coping hidden quiz, we receive error and when we try to Show we receive error, but then we tried Make available then our quiz has become visible and we can access grades and we can even use Show quiz, everything was OK. But this procedure didn't help us in other courses. I think that problem is when coping hidden items such quiz, topics or course. You can try to Show course, activity or topic, maybe this will solve the problem

Ivica--Well, I'll be!  We have been, sporadically, getting the "Invalid course Module ID" error ever since we upgraded Moodle to 3.6.1.  I tried your work around.  I went into a course and hid the activities and then un-hid them.  I can access Grades, Quizzes, etc without getting the error.

Kudos to you.  This has caused a lot of stress for us.  This definitely is not a fix, but it helps us move on.

Hi!

Also, we have tried backup/restoring and in some course, this was also helpful, in restored course we have grades and we can access every quiz without problem.

The hiding and showing of the module worked for a quiz without errors ONLY for when I (administrator) changed my role to student.

When a student logs in and takes the quiz - even one they have not taken before - the same error occurs.

Hi!

Moodle has corrected this error. On https://tracker.moodle.org/browse/MDL-64878 you can see that in 3.6.3 version it will be fixed. First try on test server than on production.

I installed Moodle 3.7.1+ on Centos 7.6.1810, with PHP 7.3.9, Apache 2.4.6-89, MariaDB 10.4.7.

I had a significant number of errors when data needed to be inserted into a table (filters installation, importing Aiken formatted questions, adding resources to courses, etc).

All these were sorted out when I downgraded MariaDB to 10.3.17. It seems there is an incompatibility between latest version of Moodle and latest version of MariaDB.

Good luck with the course.
