Mavros Load plan/waypoints problem

Hi everybody!

I trying to use a plan file using mavros by the command mavros mavwp load file path. I created the plan/waypoints file using Qgroundcontrol, creating waypoints and using save as.
However, i had this error when I used mavros.

Also, I tried using a predefined this plan, but I had the same issue.

Any suggestions?

Thanks
