Hi,

I have been testing Gremin and JanusGraph, when I execute following command, I get an exception only when I use string "asdf" as key.

g.addV("ccr_node").property("asdf","asdf").next()

I have tried some other 4 letter versions with different endings and beginnings but I only get this error when I use "asdf".

Any idea what is wrong here?

For those wondering about that html:

This question looks specific to JanusGraph - you should probably ask about it on their user list. I'm not aware of any reason why you can't use a property key of "asdf" while other random keys will work. Note that JanusGraph does have a schema so I could imagine a key being rejected if you didn't have JanusGraph or its schema configured the right way, but again, probably a question for JanusGraph folks.
