Unable to decipher error

[dataskills]

I am trying out this library with a neo4j aura instance. I can't get it working and I have not been able to understand the error I am getting, any insight would be much appreciated, this is what I am getting:

Exception 'Laudis\Neo4j\Exception\Neo4jException' with message 'Neo4j errors detected. First one with code "" and message "Read error"'

in /Users/dataskills/Sites/localhost/myApp/vendor/laudis/neo4j-php-client/src/Bolt/Session.php:125

Stack trace:

I am just trying to run a simple CREATE statement to test things out and I am getting the exception with no code and a "Read Error". The error does not contain any useful description. The node was not created (I checked using the browser), so I don't even know what it's tryig to read.

After further review, I can see that the function unpackProtocolVersion() is failing at line 161 when it is trying to read the protocol version from the connection during the handshake process (I think). I don't know enough about the bolt protocol to know for sure. Has anyone tried to connect with Neo4j Aura before?

Hello @dataskills,

Thank you for posting this issue. It looks like a more complex issue. I will first have to acquire access to an aura instance. Forgive me, but this issue might take me a few days to fix.

In the meantime, can you check if the HTTP protocol works at least?

Kind regards,

Ghlen

@dataskills Are you using Aura Free, Aura Professional or Aura Enterprise? @transistive HTTP is not available with Aura at the moment.

Also, what connection URI (scheme) are you using, @dataskills?

[dataskills]

I am using Aura Free to test the service. Forgive me if I am mistaken but it looks like the only scheme I can use is the neo4j scheme, correct? See connection URI in the image:

Is this type of connection not supported? My goal is to find a hosting service, if neo4j aura is not viable can you suggest an alternative? I appreciate your responses @fbiville and @transistive .

[fbiville]

It's not completely supported as of now, but I know @transistive is actively working on it. I'll let him give a more definitive answer.

[dataskills]

Ok, thank you. I hope @transistive can shed some more light on this when he has time. In the meantime can you suggest an alternative to neo4j aura for hosting?

[transistive]

Hi @dataskills. We have been working the entire day to find the issue and am happy to report we have found the culprit! It was due to some complex SSL configuration which only aura needed to function correctly.

You can expect the bugfix within a few hours. :+1:

Thanks again for bringing this to our attention.

[dataskills]

Very cool, I appreciate it. I look forward to the fix. Cheers.

[transistive]

The bug is fixed! Feel free to update to version 2.0.4 to enjoy neo4j aura and php

[dataskills]

The fix works! Thank you @transistive, great work!
