Repro steps:

1. Please clone this project:
   https://github.com/zhangguanghuib/NewCommerceSDK/tree/main/POS_Samples/POSExtensions/MultiPkgs1

   2. Please notice,
      GHZ.StoreHoursSample.DataModel: contains the Entity and Request/Response
      GHZ.StoreHoursSample.CommerceRuntime: Request Handler, it is a Scale Unit Package
      CommerceRuntime: Send Request from this package.

and One Store Commerce Package:

3. Log in POS, go to Search View, click to open the view, and then click Ping Test Button:
   
   

4. Debug the code:

You can see the request send from one package:

and it really can find the request handler in another package:

But you can see in this line:

if (reqType == typeof(GetStoreHoursDataRequest))

This compare will return false and then finally it will show this request will not be supported

Question:

Can you please confirm why send request from one package, if the request handler in another package, the request will not be handler?
