ProGet -> Helm: Unable to cast object of type 'System.String' to type 'Inedo.ProGet.Feeds.IComparablePackageVersion'.



  • Hi

    We're encountering the following error with our helm-chart-feed when trying to download a chart (does not matter if using helm-cli or direct http-request):

    Message: "An error occurred processing a GET request to https://packages-01.net.ingtes.ch/helm/helm-dev/ingtes-success-mobile-host/0.2.0/ingtes-success-mobile-host-0.2.0.tgz: Unable to cast object of type 'System.String' to type 'Inedo.ProGet.Feeds.IComparablePackageVersion'."
    Details: "System.InvalidCastException: Unable to cast object of type 'System.String' to type 'Inedo.ProGet.Feeds.IComparablePackageVersion'.
    at Inedo.ProGet.Feeds.StandardPackageFeed`3.GetDownloadBlockReasonAsync(IStandardPackageMetadata package, Boolean bypassFreeEditionCheck)
    at Inedo.ProGet.WebApplication.FeedEndpoints.Helm.HelmFeedHandler.ProcessChartArchiveRequestAsync(AhHttpContext context, WebApiContext apiContext, HelmFeed feed, String name, String version)
    at Inedo.ProGet.WebApplication.FeedEndpoints.Helm.HelmFeedHandler.ProcessRequestAsync(AhHttpContext context, WebApiContext apiContext, HelmFeed feed, String relativeUrl)
    at Inedo.ProGet.WebApplication.FeedEndpoints.FeedEndpointHandler.FeedRequestHandler.ProcessRequestAsync(AhHttpContext context)
    

    We strongly suspect this is a classic c# casting bug introduced with 2023.0.0.

    • The issue is reproducible whenever we upgrade from v2022.0.29
    • Downgrading to v2022.0.29 resolves the issue

    More info:

    • Installed on Windows Server 2022 with Inedo Hub
    • The last version working for us is 2022.0.29
    • Affected Version: ProGet 2023.0.0 and higher

    Thx for having a look.

    Kind regards

    Hi @h-morgenthaler_3015, we are currently investigating this. ,It sounds like an issue we fixed in ProGet 2022 already, but maybe it didn't get merged over. Please stay tuned.

    Hi @h-morgenthaler_3015,

    Alana was correct, the change was not merged into the 2023 release. The fix, PG-2350, will be released on Friday in ProGet 2023.4. If you need it earlier than Friday, I can push a pre-release version of ProGet 2023.4 for you. Please let me know!

    Thanks,
    Rich
