Homework 2.3 ..note for HR database

I went exactly through the same assumption Matthias_17852 described in his note.(https://www.mongodb.com/community/forums/u/Matthias_17852)
I should have come to the forum much earlier to understand the meaning of “read”

Anyway after dropping and recreating again the EMPLOYEEPORTAL my second attempt failed again.

My last guess was that I should use “HR”, instead of “hr”… and that worked!
I’m sharing this so you do not go through the same mistake :slight_smile:
