@brajaram Was there no more output, like a traceback?

[brajaram]

Below is the traceback:

Thank you for the traceback.

I think that looks very much like a bug in the neo4j-driver module. I will look in to it if I find the time.

[zupd]

When using migrate command:
Exception TypeError: "'NoneType' object is not callable" in <bound method DirectDriver.__del__ of <neo4j.v1.direct.DirectDriver object at 0x7f3b249a6bd0>> ignored

[johanlundberg]

From what I have been able to find this is an exception thrown from the neo4j driver when the connection is already closed. The migration is successful anyway, right?

[zupd]

Im not sure. When bootstrapping I get this error:

So its not working at least

[johanlundberg]

Ok, you need to change cypher.default_language_version to 3.1 in neo4j.conf, please see #11.

[johanlundberg]

I found a usage of the now deprecated START cypher statement. So now the above comment can be disregarded.

I still see the Exception TypeError: "'NoneType' object is not callable" in <bound method DirectDriver.del of <neo4j.v1.direct.DirectDriver object at 0x7f3b249a6bd0>> ignored error but the app works as expected,

[zupd]

I am using Docker though, I can't change the neo4j.conf then, right?

[johanlundberg]

Well you can mount a config file from the outside, but that is beside the point now after my last update.
Just do a git pull and try the bootstrap again.

[zupd]

I just ran another docker container with version 3.1 so working now

[zupd]

However the website is really slow, and cant load the movies or persons page at all. loads forever. does it work for you?

[johanlundberg]

Yes, it works for me. I just ran through the tutorial with a new clone of the repo and the latest Neo4j docker image (3.2.1).

[zupd]

cloned new repo and ran it just like you, but I still cant get into the movies or persons page on the website. The homepage and admin page works fine though

[johanlundberg]

Can you open a new issue to discuss this problem?
