I found the solution
Once you change the SECRET_KEY and MFLIX_DB_URI in dotenv_win file then navigate to that folder from command prompt and run the ren dotenv_win .env which it remove the dotenv_win name and reset to .env

env

Thanks Vimal,

I re-read the full instructions set word by word and able to figure it out…

my problem was that I had taken another course where I had used the ATLAS account and I thought it was the same, it wasn’t so after I re-read the instructions and stopped my ego from getting in front of my nose, I then was able to reason it out.

One thing I did find troublesome was the where the examples were confusing, but again after re-reading the instructions and several hours of testing I was able to figure it out. another thing I find surprising is how much this course is sooo different from the old 121 JavaScript course with so much hidden under the covers, but the fact that the DB is being manipulated in such a clear manner makes me very happy.

I finished all of the labs by Sunday night and felt very good. I’m linking this course really well so far.

Thanks for your help.

Vimail,

the one test I could not get going was the connection-pooling, but I’ll work on that some other time.
