servers.create doesn't appear to be handing in user_data

[paul42]

I have cloud-init on my images and when I use the UI and paste the yaml into the user_data field it spawns properly, but when I attempt this server data object:

var server_data = { name: "apiRoleTest1", flavorRef: '1', imageRef:'long guid', metadata: { "login_users": "etc" }, user_data: yamlString };

I am not getting any results or errors after logging onto the server.

thanks in advance
