Nodes not connecting through remap in launch file

edit

Hello I am using ROS kinetic with ensenso/ros_driver and akio/mask_rcnn_ros, both the master branch. Running on Ubuntu 16.04 kernel version 4.15.0-46-generic.

I am using an Nvidia RTX 2080 ti with cuda 418.39

I am trying to connect the ensenso_camera_node to the mask_rcnn_node using a launch file in which I remap the input of the model to the output of the camera.

<launch>
    <remap from="~input" to="/rectified/left/image"/>  
    <arg name="configuratie" value="$(find ensenso_camera)/configs/configuratie.json"/>
    <node pkg="ensenso_camera" type="ensenso_camera_node" name="ensenso_camera_node">
    <param name="settings" value="$(arg configuratie)"/>
    </node>
    <node pkg="ensenso_camera" type="request_data" name="image_data"></node>
    <node pkg="tf" type="static_transform_publisher" name="ensenso_optical_frame" 
           args="0 0 0 0 0 0 world ensenso_optical_frame 100"/>
    <node pkg="mask_rcnn_ros" type="mask_rcnn_node" name="mask_rcnn"></node>
</launch>

The nodes are started without an error, however, when I check with roswtf it states that either the input of the model is not connected, or that the camera and the model should be connected but aren't depending on the position of the remap statement in the launch file.

WARNING The following node subscriptions are unconnected:
    * /mask_rcnn:
       * /mask_rcnn/input

or

ERROR The following nodes should be connected but aren't:
   * /ensenso_camera_node->/mask_rcnn (/camera_image)

I am guessing that I am making a mistake in the remapping of the topics but my experience with ROS is about as much as can be seen above so I am not sure. Hopefully someone can help me out with this.

Thanks in advance!

With the remap still in place the rosnode info mask_rcnn returns:

With remap removed rosnode list returns:
