ServerBinding object is not JSON serializable

[Simon_Tremblay]

I have Nuxeo 6.0.0 platform with Nuxeo Drive plugin 1.4.3 installed. I installed Nuxeo Drive client for Ubuntu (14.04) as mentionned here [http://doc.nuxeo.com/display/USERDOC60/Nuxeo+Drive][1]. [1]: http://doc.nuxeo.com/display/USERDOC60/Nuxeo+Drive

I've got that error in terminal:

I don't know if it is a problem of version compatibility between nuxeo drive client and plugin but it isn't mentionned that it needs to be in phase.

Finally I found a solution to my problem. From here: http://answers.nuxeo.com/questions/10614/nuxeo-drive-doesnt-start-in-ubuntu-nor-windows

It is mentionned by ataillefer that master branch of nuxeo drive client isn't always stable. So I installed 1.4 branch and it works well now.

Maybe it would be useful to update the documentation.

Yes you're right, just updated the documentation.
