Unrecognized message type in ros simulink

I am having problems building and running my simulink model. I am try using a custom message in a service but when I try to buid my node it give the following error:

Top model targets built:

Model         Action  Rebuild Reason                                    
========================================================================
test_service  Failed  Code generation information file does not exist.  

0 of 1 models built (0 models already up to date)
Build duration: 0h 0m 15.279s
Unrecognized message type simple_test/MyTest. Use rosmsg list to see available types.

Right now I am just trying to get a toy model working so I can get my real controller working that is much more complex.

My custom message is the following called simple_test/MyTest.srv:

int64 a
int64 b
---
int64 sum

I used this to message to replace the model in ros_twoint_service_simulink_example.slx

when i run rosmsg list I get the following:

other message
simple_test/MyTestRequest                                      
simple_test/MyTestResponse        

here is a screen shot of my current workspace:

Hello Nathaniel,

This looks like a bug in ROS Toolbox "Localhost" deployment workflow.

Thanks for notifying us. As a workaround, can you please deploy the code using "Remote Device" on a VM or your robot.

To deploy the code on a remote device, in Simulink toolstrip, ROS tab, select "Remote Device" option from the "Deploy to" drop-down section in CONNECT tab.

You can use "Manage Remote Device" button to set the IP Address, user, password of your VM or remote device.
