How to Customise Copilot for Dynamics 365 Finance

Posted on by Sophs@4Sight 92
Good day.  We are trying to customise Copilot for D365 Finance.
I am following the tutorial (Tutorial: Create AI plugins for copilots with finance and operations business logic) (https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/copilot/tutorial-create-ai-plugins) to customise Copilot.
Part of the process is to create a class to implements the ICustomAPI.  However I get an error when trying to  create my Deployment Package. 
"D:\a\8\NuGets\Microsoft.Dynamics.AX.Platform.CompilerPackage\DevAlm\Microsoft.Dynamics.Framework.Tools.BuildTasks.targets(85,5): Error : Fatal: dynamics://Class/ACCAICustomAPICalculateCustomerBalance(4,59) - Interface 'ICustomAPI' is not found." On investigation we found the the ICustomAPI is empty.
There is no code just the run method but that is also empty.
 
Do I need to replace this or what am I missing.  Please can you advise.
If anyone has any other tutorial to teach us the correct way or more understandable I would greatly appreciate.
 
Kind regards

    Interfaces don't contain code; they just describe what methods (with what parameters etc.) a class needs to have. Implementing an interface means creating a class that declares that it implements the interface. For example: 
    class MyAPI implements ICustomAPI
    The compiler checks whether the class has all the methods defined in the interface. In your case, you must implement the run() method, otherwise your class fails to compile.

    The error messages says that the interface wasn't found at all. It suggests that your code can't be compiled by the build server. If you can successfully compile it locally, check the F&O version used by the build agent. You probably have an older version there. The version must be at least 10.0.40 proactive quality update 1 (PQU-1) with platform version 7.0.7279.80.

    It's an interface (methods) that you need to implement in classes that implements it. It's supposed to be empty.
     

    Edit: Do as Martin says. Since the compiler is on the D drive, it highly signifies that you are using a hosted agent in Azure. You need to update your pipeline. Since it's splitting again, you might have to follow this guide: Dynamics 365 F&O: 10.0.40 Service Update Split Nuget Package | Software Development & Technology (anthonyblake.github.io)
