Thanks for your question. However we ask that you please ask questions on http://answers.ros.org following our support guidelines: http://wiki.ros.org/Support
ROS Discourse is for news and general interest discussions. ROS Answers provides a forum which can be filtered by tags to make sure the relevant people can find and/or answer the question, and not overload everyone with hundreds of posts.
If you’d like you can reply with a link to your answers.ros.org question, but in the future please start there. And I’d strongly recommend that you include some more details about how to reproduce your issue. It looks like you are using incompatible versions of code so you’ll need to explain explicitly what versions of code your running on your system and in your workspace.
