When I try to initiate and connect with a new driver and run "npm run test 01"
I get test fails.
I checkout the git checkout 01-connect-to-neo4j and add my uri, user, password and run npm run test 01 and it passes.
So I copied the entire file and went back to the main branch and with the neo4j.js file removed all the content and pasted in the code that worked . Ran it - and it FAILED... stuck - help
My apologies: you are correct - I left out some details
Course is:
set up the neo4j.js file
in terminal - npm run test 01
> neoflix-api-node@0.1.0 test
> node --experimental-vm-modules node_modules/jest/bin/jest.js 01

@DrAli - Which course are you talking about specifically? Also - you mention failures, but you don't share what those failures are. Kind of hard to help...
Can you share your neo4j.js file please?
@DrAli ,
Modify the connection string for the driver to match your sandbox instance as explained here:
https://graphacademy.neo4j.com/courses/app-nodejs/1-driver/2-connection-strings/
Our sandboxes are currently in the process of migrating to Neo4j 5.4 but the connection for the driver should work as it did for Neo4j 4.x.
I did follow those instructions.
I just copied and pasted from the other branch - and got it to work that way. There are differences in the code that may explain the first one failing - but those changes were not part of the assignment - specifically the export closeDriver function lines 59 to 61
you can only upload jpegs here - but you can access the file if you are in the course - by using the git checkout 01-connect-to-neo4j
You should be able to copy and paste your code into the reply window and wrap it in backticks to format it correctly. I would like to understand what has happened in your case so I can make sure that others don't run into the same issue.
