Ticket: Migration Problem

MongoDB University M220JS: MongoDB for Javascript Developers
#1

The following query runs correctly when I do it in mongodb atlas but returns 0 documents when i run it on my console

predicate  { lastupdated: { '$exists': true, '$type': 'string' } } 
projection  { lastupdated: 1 }


$node movie-last-updated-migration.js

Found 0 documents to update
No documents to update

My connection is working correctly, the cursor is an empty array [ ] , I don’t know why it is unable to find the required documents

I am also getting the same error. Please let me know if you find solution.

You have to copy values of MFLIX_DB_URI, MFLIX_NS from .env file and set them to host and namespace respectively
The migration js file is run in isolation and hence these values won’t be available in process.env object.

Thank you @chinta_14978, I had not set the MFLIX_NS

Hi did it work for you when you set MFLIX_NS, there is no namespace declared. where does it go?

Hi @Melakeselam_Moges_Mengistu_42275,

Is the code not working for you even after setting MFLIX_NS? Let me know so that I can help.
