ProGet 2025.12 Published date is default value on packages from connector feed

d.mischke_3966

Hello there,
I use a Connector to access packages from a third party V1 Nuget Feed.
the published date shown in the package metadata page defaults to "01.01.0001 01:00:00" on all packages that are not pulled to the feed.
If I connect a nuget client to the proget feed I get exceptions when the client tries to query the available package versions.
The exception thrown is:
The UTC time represented when the offset is applied must be between year 0 and 10,000

The Screenshot is from NuGet Package Explorer, but other clients show this error as well.
I hoped to use this approach to get Nuget V3 API functions on a legacy feed.

Hi @d-mischke_3966,

When you say a "v1 NuGet feed", do you really mean the ancient version (i.e. used from 2010 to 2015)?

I don't think ProGet has ever supported that if so.

Ultimately it sounds like there is a problem with the API though -- 01.01.0001 01:00:00 is not a valid date.

Thanks,
Alana

I do not know exactly witch api version the feed is hosted on. I guessed it by the Version in the URI and that the feed is xml based.

This is the landing page when I type the feed URI in my browser.
Everything else seems to work just fine. But if you say it is out of support, then I gonna pull all packages from the connector to my feed.
Also I am trying to convince the owner of the feed to update his server and hope that I don’t run out of disc space.

Thanks,
Dirk

Hi @d-mischke_3966 ,

I don't really know... based on the url it does like V1 to me, but the response looks like V2 API looks like (it's an ODATA/RSS style). I don't know what V1 looks like, it's before all of our times :)

Anyway I would ask them to investigate the issue. V2 has been deprecated for over 5 years now, so we don't wanna make changes, especially to work-around a "bad" third-party feed.

Thanks,
Alana

ok thanks for looking in to this.
fyi: I think I found out what kind of feed ist used. It seemed to be a Chocolatey Simple Server https://github.com/chocolatey-community/simple-server/tree/master
So it is V2 API based, but with some chocolatey customizations. This project seems to be deprecated by the chocolatey team.
