  • This exception is thrown by ABP’s (dynamic) HTTP client proxy when it can’t find a matching action inside the server’s API definition (/api/abp/api-definition) for the method you’re calling:
    • The API description of the ... IWorkspaceAppService.GetListAsync method was not found!
    • The warnings also confirm the same root cause:
      • Could not find ApiDescriptionModel for action ... Workspace, May be the generate-proxy.json is not up to date.

  Fix (MVC tiered / separated host)

  1. Regenerate the proxy definition file(s) used by your MVC app

  • In the solution root (where ABP CLI can find your apps), run proxy generation again so the generated proxy metadata matches the RC2 backend:

  abp generate-proxy -t csharp -u https://localhost:44340/
  

  If your solution is modular / the endpoints are in a specific module, generate with module name:

  abp generate-proxy -t csharp -u https://localhost:44340/ -m YourModuleName
  

  2. Ensure the MVC app uses the updated generated proxy JSON

  • Those warnings typically happen when:
    • the MVC app still has an old generate-proxy.json (or app-generate-proxy.json) embedded, or
    • the file exists but your app isn’t adding it to the Virtual File System.

  In your MVC (client) module, keep (or add) the VFS embedding:

  Configure<AbpVirtualFileSystemOptions>(options =>
  {
      options.FileSets.AddEmbedded<YourMvcClientModule>();
  });
  

  3. Clean & rebuild

  • Delete bin/obj (or dotnet clean), rebuild, restart both the Host and the MVC app.
  • Then retry “Get workspaces”.

  4. If you generate proxies “without contracts” If you are using static proxies without referencing the contracts package, you must also configure the proxy configs as described in ABP docs (otherwise method/action resolution can fail at runtime).

  Why this happens in 10.2.0 RCs

  In RC builds, API surface and route/action metadata can change between RC1/RC2; if your MVC app still carries proxy metadata generated against an older build, ABP can’t match IWorkspaceAppService.GetListAsync to any action in the API definition model and throws exactly this error.
