At a glance

There are not enough weekly instances of this lesson to spread across the required minimum number of days.

What causes this error

This lesson has a rule requiring it to be spread across a minimum number of different days per week (COURSE_MIN_DAYS). However, the lesson only occurs a few times per week — fewer than the required minimum days. You cannot place 2 lessons on 3 different days.

How to fix it

1. Increase the lesson frequency — Add more weekly occurrences of this lesson so it can be placed on the required number of days.
2. Lower the minimum days rule — Reduce the COURSE_MIN_DAYS rule value to at most the number of weekly instances.
