      When following the guide on how to setup Importing from Other Feeds/Servers we get a (500) Server Error.

      We get this error after we click the button "Import packages" or "Download Package From Another Service" (the first when we do this with a Docker feed, the latter when we try to set it up for a Nuget feed).

      The error message we see is: Unable to cast object of type Inedo.Extensions.Credentials.UsernamePasswordCredentials' to type 'Inedo.ProGet.FeedImporters.FeedImportService'.

      Is this a known problem? Does anyone have a suggestion on how to fix it?
      We face the same problem with both version 2025.21 and 2025.22
      This is the complete stacktrace (redacted confidential information):

      An error occurred in the web application: Unable to cast object of type 'Inedo.Extensions.Credentials.UsernamePasswordCredentials' to type 'Inedo.ProGet.FeedImporters.FeedImportService'.

        Hi @gbeckett,

        Would you be able to provide us with a screenshot of the manage credentials page? https://proget.***REDACTED***.services/administration/credentials?showFeedImportServicesOnly=True

        I think I see what could cause this error, but it would help us to pinpoint the issue.

        Thanks,
        Dan

            Hi @gbeckett,

            Thanks for sending that screenshot. It is not what I expected to see, but I can see why that issue is happening now.

            I have created ticket PG-3234 to fix this issue. It will be released this Friday in ProGet 2025.23.

            Thanks,
            Dan

                Unfortunately we still see the exact same behaviour:

                  Hi @gbeckett,

                  It looks like there was a merge issue and part of this fix was undone. I have created a new ticket, PG-3240 to fix it. If you would like, I can create a pre-release of ProGet 2025.24 with the fix that you can install now. If not, the fix will be released at the end of next week in ProGet 2025.24.

                  Thanks,
                  Rich

                    Thank you @rhessinger

                    If you could provide us with a pre-release so we can test the fix that would be great.
