Could not connect to neo4j #45

Closed gaurav-gogia closed 6 years ago

gaurav-gogia commented 6 years ago

Hey, so I'm just getting started with this bolt driver for neo4j and looks like I cannot connect to the db. I'm using neo4j-community version 3.3.3

I've made sure that neo4j console is running and is accepting connections on port 7687

But looks like it's not really working. Below is the code & stack-trace. Am I doing something wrong?

Thanks ^.^

func main() {
 con := createConnection()
 defer con.Close()
}

func createConnection() bolt.Conn {
 driver := bolt.NewDriver()
 con, err := driver.OpenNeo(URI)
 handleError(err)
 return con
}

And here are the error(s) that I've got:

panic: An error occurred initializing connection
        An error occurred decoding ack failure message response
                Couldn't read expected bytes for message length. Read: 0 Expected: 2.
Internal Error(*errors.errorString):driver: bad connection

Well, looks like I was using wrong URI. So here it is in case someone gets the same problem:

Use something like this while connecting with your db: bolt://username:password@localhost:7687
