Impossible to connect to Aura-hosted database

[neverstew]

Bug Report

It's impossible to connect to a Neo4J Aura instance using this driver in a node runtime.

Here's a list of existing issues that reference problems connecting:

• Unable to access 3.5.28 cluster with 4.4.5 driver #963
• [QUESTION] Unable to connect to Neo4j Desktop graph instance #560 (indirectly, people struggling with understanding the errors)

This can be reproduced reliably using this minimal reproduction.

This is the error

Node.js v19.8.1

I have gone down the rabbit hole on this one and it's extremely frustrating! I have managed to trace the problem to prove that it reliably:

1. calls to start the Bolt handshake, never reaching inside either the resolution or rejection callback functions.
2. Ends up calling _handleConnectionTerminated with the spurious 'SessionExpired' code.

My Environment

Javascript Runtime Version: 19.8.1
Driver Version: 5.7.0
Neo4j Version and Edition: unknown - created 2023/04/28
Operating System: MacOS 12.4

@neverstew, can you try with the latest version of the driver?

We had an issue with the 5.7.0 version which is already fixed in 5.7.1, but you can move directly to 5.8.1 if you want.

Thanks @bigmontz, just got around to trying it out on 5.8.1 and 5.9.1 and all looks good!
