ERROR when publishing on topic joint_trajectory - Received trajectory with no-zero start time that ends in the past.

[Robeatrice]

Hello,

i am working on programming the IGUS REBEL KID with 4 Axis via ROS2.
Since I am new to ROS2 and IGUS i want to try to publish a joint trajectory message.

For receiving I launch in Terminal1 by "ros2 launch irc_ros _bringup rebel.launch.py rebel_version:=01 "

So far I only get one warning: allow_nonzero_velocity_at_trajectory_end is set to true. the default behavior will change to false.

After the launch process has finished cleanly I get the error that no message or not a full message is received

When I then start this command in terminal2

I get the Error: Received trajectory with no-zero start time that ends in the past.

I already synchronized the time of my computer and the robot. I have no idea what to do next.

Can someone help me with this Error?

I am using Linux Ubuntu 22
ROS2 Humble
