Using node-red in Bluemix,I get this error: The Workspace contains unknown node types

I am using node-red in Bluemix cloud and I am getting this error starting today. It worked last time and I am not able figure out why. I re-created the nodes but got the same error. The error prompts to Twitter.in node. Can someone help me out with this?

Without seeing the error you are getting it is difficult to tell what is causing it, but I suspect that you are being prompted for a twitter id, and permissions to view / post to a timeline. You probably saw this initially and set it, and forgot about it. Subsequently the original permission / token has expired you are being prompted to reissue the permission.

Do you have a period "." in the twitter in node definition? It should instead be "type":"twitter in" with a space and no period.
