The final version of the application does not work when using code from the course. #17

Closed AdrianusWest closed 6 months ago

AdrianusWest commented 1 year ago

The code in the repository on the githab and in the course module on the site is different.

Registration and authorization do not work. I admit that I might have done something wrong. Below is the terminal output.

The above exception was the direct cause of the following exception:

That looks like a problem connecting to your database. Did you get an email about your Sandbox being terminated? Or if you completed the course, the database may have terminated automatically.

Try double-checking the details in your .env file with the values in the Your Neo4j Sandbox lesson, or head to Neo4j Sandbox and create a new Recommendations sandbox.

Thanks! I'll try with a new instance of the sandbox, I think that's really the point.
