Downloading Leptonx still not possible #10120

See f.e. https://abp.io/support/questions/8331/Exception-of-type-%27VoloAbpStudioAbpStudioException%27-was-thrown-for-LeptonX-theme

If I run; abp get-source Volo.Abp.LeptonXTheme --version 3.3.4

I still get this error:

Downloading source code failed for: Volo.Abp.LeptonXTheme Volo.Abp.Studio.AbpStudioException: Exception of type 'Volo.Abp.Studio.AbpStudioException' was thrown.

What can I do?

    1. Solution
    • Use the correct module name and latest version that contains the fix. For LeptonX, do not append “.Pro”. Run:
      • abp get-source Volo.Abp.LeptonXTheme --version 4.2.2
    • If you specifically need 3.3.4: that feed no longer serves LeptonX source via get-source due to backend changes. Use a supported version instead. 4.2.2 (or later) is confirmed to work for LeptonX.
    • If you need the Angular packages’ source (beyond volo-lepton-x), add them explicitly with source:
      • abp add-package @volo/abp.ng.lepton-x.core --with-source-code
      • abp add-package @volo/ngx-lepton-x.core --with-source-code
      • abp add-package @volosoft/abp.ng.theme.lepton-x --with-source-code
    • If any add-package or get-source returns AbpStudioException/HTTP 500, it’s a transient server-side package listing issue. Retry targeting a known-good version (e.g., 4.2.2) or one version earlier (e.g., 4.2.1) and then upgrade.
    • Ensure you are authenticated with an active ABP Commercial license in the CLI (abp login) before downloading commercial sources.
    • Update the CLI to the latest:
      • dotnet tool update -g Volo.Abp.Cli
    • Summary of working commands:
      • abp login
      • dotnet tool update -g Volo.Abp.Cli
      • abp get-source Volo.Abp.LeptonXTheme --version 4.2.2
      • abp add-package @volo/abp.ng.lepton-x.core --with-source-code
      • abp add-package @volo/ngx-lepton-x.core --with-source-code
      • abp add-package @volosoft/abp.ng.theme.lepton-x --with-source-code
