Using abp get-source Volo.Abp.LeptonXTheme --version 9.2.2 also does not work for us. [19:16:17 INF] You are running the second generation of the ABP CLI. If you're interested in the legacy CLI, see https://abp.io/new-cli [19:16:17 INF] Downloading source code of Volo.Abp.LeptonXTheme (v9.2.2) [19:16:17 INF] Output folder: C:\repos\tmp\abp922\lepton [19:16:24 ERR] Downloading source code failed for: Volo.Abp.LeptonXTheme Volo.Abp.Studio.AbpStudioException: Exception of type 'Volo.Abp.Studio.AbpStudioException' was thrown. at async Task Volo.Abp.Studio.Modules.Installing.SourceCodeDownloader.DownloadSourceCodeAsync(string moduleName, string targetFolder, string version, bool includeNightly) at async Task Volo.Abp.Studio.Cli.Commands.StudioGetSourceCommand.ExecuteAsync(CommandLineArgs commandLineArgs) at async Task Volo.Abp.Studio.Cli.StudioCliService.RunInternalAsync(CommandLineArgs commandLineArgs) at async Task Volo.Abp.Studio.Cli.StudioCliService.RunAsync(string[] args)

We really need the code asap since we have a customized account layout based on lepton x layout in a production site which needs to be upated. In case you can email me to nico@chrobyte.de

Kind regards Nico

    • This error typically occurs when there is a problem with authentication or license validation while downloading ABP Commercial module source code (such as LeptonX Pro) using ABP Suite or the CLI. The error message "'<' is an invalid start of a value" usually means that an HTML error page (often a 403 Forbidden or similar) was returned instead of the expected JSON, which is often due to a failed authentication or expired/invalid license.

    • To resolve this issue, follow these steps:

      1. Run abp logout in your terminal to clear any cached credentials.
      2. Run abp login and authenticate again with your valid ABP Commercial credentials.
      3. Retry the source code download using Suite or the CLI.
    • If you are still unable to download the source code after re-authenticating, ensure that:

      • Your ABP Commercial license is active and valid for the LeptonX Pro module.
      • You are using the correct module name and version (matching your license and project version).
      • There are no network issues or firewalls blocking access to abp.io.
    • If the problem persists after these steps, please contact Volosoft support directly with your license details for further assistance.

    same error. It's downloaded any other versions, tried 4.3.0-rc.1 and 4.0.0-4.2.0 Any other modules downloaded normally. But LeptonXTheme pro and lite v4.2.2 return this error

    you have 2 organizations. the first one is "AKA" and it's expired. probably that's why you cannot get the new source-code. login again via ABP CLI

    This issue is not related to Login info. the problem is module name. ABP Suite (v9.1.0) request old name Volo.Abp.LeptonXTheme.Pro

    below commands works normally: abp get-source Volo.Abp.LeptonXTheme abp get-source Volo.Abp.LeptonXLiteTheme

    The source code download function for the LeptonX theme has been fixed. Please try again, It works for both SUITE and CLI.

    Thanks.
