canopen motor node exit with error code -6

edit

When trying to initialize a canopen_motor_node to control a CiA402 compliant stepper motor controller (Nanotec C5-E-1-09) I am met an error code -6. When running my launch file:

<?xml version="1.0"?>
<launch>
  <!-- send urdf to param server -->
  <param name="robot_description" command="cat '$(find nanotec_ros)/urdf/urdf.xml'" />

  <node ns="nanotec_stepper" name="driver" pkg="canopen_motor_node" type="canopen_motor_node" output="screen" clear_params="true" launch-prefix="">
    <rosparam command="load" file="$(find nanotec_ros)/config/nanotec_node.yaml" />
  </node>

</launch>

With the following .yaml file:

bus:
  device: can0 #socketcan network  
  master_allocator: canopen::SimpleMaster::Allocator

sync:
  interval_ms: 10  
  overlfow: 0

nodes:
  nanotec_stepper:
    id: 1
    eds_file: "$find(nanotec_ros)/config/C5-E-1-09.eds"


defaults:
  ### 402
  motor_allocator: canopen::Motor402::Allocator
  pos_to_device: "rint(rad2deg(pos)/0.18)"
  pos_from_device: "deg2rad(obj6064)*0.18"
  vel_to_device: "rint(rad2deg(vel)/0.18)"
  vel_from_device: "deg2rad(obj606C)*0.18"
  eff_to_device: "rint(eff)"
  eff_from_device: "0"

I receive the following output:

I have tried multiple .eds files and none of them work. I checked my .eds file with the eds file checker tool and there didn't seem to be any issues.

I have a similar error to another topic however I wasn't able to solve my error looking at the solution.

My .eds file is on github
