Hi,
while deleting a course with: `tutor local run cms ./manage.py cms delete_course course-v1:COURSENAME’ I run into the following exception.

MeiliSearch should be version: v1.8.4
Which version am I supposed to run, and how to update?

Are you sure you want to delete course course-v1:COURSENAME? [y/N] y
Are you sure? This action cannot be undone! [y/N] y

If someone ever has the same issue, I fixed it by connecting to the Meilisearch container and deleting the entries by hand.

curl -X DELETE 'http://localhost:7700/indexes/tutor_course_info/documents/THE_pk1_VALUE_OF_THE COURSE' -H 'Authorization: Bearer YOUR_TOKEN'
