rosservice unable to load type, and yes I've sourced... [closed]

edit

I have a package with two nodes. One hosts a service that takes throttle and steer, and publishes a drive command. The other makes use of this service. The the client node can use the service just fine, but rosservice can't find the service type. I promise I've sourced the environment.

The node hosting the service,

bool handle_drive_request(ball_chaser::DriveToTarget::Request &mreq, ball_chaser::DriveToTarget::Response &mresp ) {
geometry_msgs::Twist motor_command;
...
auto service = n.advertiseService("/ball_chaser/command_robot", &handle_drive_request);

The client node

client = n.serviceClient<ball_chaser::DriveToTarget>("/ball_chaser/command_robot");
