No results returned, even though query is executed on server

Hi!

I created a bare ruby project using Bundler 2.5.23 on Ruby 3.3.6 with the neo4j-ruby-driver as the sole gem in the project. The Gemfile.lock says the version being used is 4.4.5. After bundle install, I then created a test file that contained the following:

require 'logger'
require 'neo4j/driver'

logger = Logger.new(STDOUT)
driver = Neo4j::Driver::GraphDatabase.driver("bolt://172.17.112.1:7687", Neo4j::Driver::AuthTokens.basic('neo4j', 'passwordformydatabase'), logger: logger)
session = driver.session(database: 'neo4j')
session.read_transaction do |tx|
  puts tx.run('RETURN 1 AS one').to_a;
end

The output of this was as follows:

The query was sent to the database, executed, returned with the correct result to the driver, and then those results were eaten.

In case this matters, I ran this on Ubuntu 24.04.1 LTS under WSL, and the Neo4J Desktop under Windows itself. I got similar results running this against an Aura instance. Replacing the .to_a with calls to .single.first causes the NoSuchRecordException. I can run cypher-shell against the DB and get the expected results, so I'm fairly confident the issue is within the driver itself, but I have no idea how to troubleshoot it. Any thoughts?

neo4jrb / neo4j-ruby-driver
