run_id on parameter server does not match declared run_id

edit

I have set up several roslaunch files to be launched at system startup using systemd. However at the startup they show the above error and fail. When I set the systemd services to be restarted on failure, launch files are relaunched when failed and work fine. What might I be doing wrong here? Declared run_id for each roslaunch seems to be different from each other at the first launch.

The error is in the following format

run_id on parameter server does not match declared run_id: 686cb5dc-01cf-11e9-ab7c-b10995016401 vs 68b27f9a-01cf-11e9-ab7c-b10995016401

Here's a sample script that runs a launch file

#!/bin/bash
sleep 1
source /opt/ros/kinetic/setup.bash
source /my/workspace/path/devel/setup.bash
roslaunch /launch/file/path/myfile.launch

Here's the format of the systemd services I use

[Unit]
Description=Unit description
Wants=roscore.service
BindsTo=roscore.service

[Service]
User=username
ExecStart=/script/that/runs/the/launch/file.sh
Restart=on-failure
RestartSec=1

[Install]
WantedBy=multi-user.target

roscore.service starts a roscore. I am using kinetic on Ubuntu 16.04.
