Error when calling /get_coordinates service

Course Support ROS Navigation In 5 Days

I launch the /get_coordinates service server like so:
roslaunch my_turtlebot_navigation get_coordinates_service_server.launch,

Then when I call the service like so: rosservice call /get_coordinates "label: 'pedestrian'"

I get this error: ERROR: service [/get_coordinates] responded with an error: b'error processing request: int exceeds XML-RPC limits'

My spots.yaml file looks like this:

Hello @dblanding ,

It looks like the problem could be related to sending an integer that is too big. For instance, the first x value is huge (it doesn’t seem correct neither):

x: 8453204346926008

Could you try reducing this number?
