Exception running any Cypher query

[dbercht]

Hey,
I'm trying to run a simple Cypher Query, but keep getting a RuntimeException with no message.

The cypher REST endpoint is running and anormCypher is pointing to the right address:

scala> Neo4jREST.baseURL
res19: String = http://localhost:7474/db/data

And the query is simple

Cypher("MATCH (n) RETURN n")()

When I run it from a running Play! 2.2.1 application, I get the following error:

And finally, the travis build shows the following error:

Does this sounds like a version issue or did I entirely miss a configuration step?

[freeeve]

the travis build is only failing for 1.0.0 (just fixed the readme image for master, thanks for pointing it out), which is the development version we've recently started developing... pushed a broken build to share with some other people working on it. (it's obviously not ready for use)

I think you need to have a trailing slash in your baseURL, although that stacktrace is really not helpful in this case. API for host connection/cypher endpoint will be better in 1.0.

Thanks! The trailing slash in the baseUrl was the issue.
Closing the issue.
