rosbag in launch file not saving properly [closed]

edit

I can successfully save data through command line tools (rosbag record -O mybag.bag /state) but when I convert this to a launch file implementation it does not save the "mybag.bag" file properly or I just don't know where this file saves to. I know the rosbag node is working because I can see it subscribing to /state in rqt_graph. Any help on this is greatly appreciated.

    <node name="actionNode" pkg="localization" type="actionNode.py"/>
    <node pkg="rosbag" type="record" name="recorder" args="-O mybag.bag /state" output="screen"/>
