Copied from MDLQA-10445 :

When I try to navigate an established lesson in this course: https://qa.moodle.net/course/view.php?id=2, I receive the following error message: "Notice: Undefined property: stdClass::$inmediatejump in /var/www/vhosts/qa.moodle.net/html/mod/lesson/locallib.php on line 3279." I click continue to proceed to the next page and I'm stuck on this part of the lesson: https://qa.moodle.net/mod/lesson/view.php?id=27&pageid=25. I click the OK button, but it just refreshes the page. I had to use the browser back button, which is not what I am supposed to do, I think.

Lesson Activity I Used: https://qa.moodle.net/mod/lesson/grade.php?id=27&itemnumber=0&userid=3 in course with id 2.

I changed the grade from None to 10 points, switched my view to the student view, ran through the lesson, and received a score.

Then, I switched back to the teacher role and changed the maximum grade to 5. It changed my score to a maximum of 5 points and recalculated my score and the percentage
