robot_localization: unable to use odometry/filtered as input

edit

Hi,

I'm using ROS Kinetic and a Clearpath Husky robot. I have an already running ekf_localization_node on my robot that gives me the base_link -> odom and outputs an odometry/filtered topic. Now, on the top of it, I want to use robot_localization to fuse global absolute data with markers.

I want to use the odometry data for my second ekf_global, hence I want the odometry/filtered topic to be subscribed by this node. Here is my launch file:

<?xml version="1.0"?>
<launch> 
<node pkg="robot_localization" type="ekf_localization_node" name="ekf_se" clear_params="true">
<rosparam command="load" file="$(find robot_localization)/params/my_ekf.yaml" />
<remap from="odometry/filtered" to="finalpose"/>
</launch>

The param file my_ekf.yaml is below:
