Error on FindPackagesById

[Guest]

I currently get the following issue in ProGet (just updated to the newest version, it didn't work in 5.2.3 either): When trying to access the FindPackagesById() endpoint for any feed I get the error:

"An error occurred getting the package: The version number provided is invalid. See https://inedo.com/support/kb/1157#semver2 for details on version number formatting restrictions."

The traceback for this (as gathered from the admin panel) is as follows:

System.AggregateException: The version number provided is invalid. See https://inedo.com/support/kb/1157#semver2 for 
    details on version number formatting restrictions. ---> System.FormatException: String is not a valid semantic version.

This happens even on a completely empty feed .

Since this function is used by nuget during the restore step, the server is essentially useless in this case.

Product: ProGet
Version: 5.2.4

Hello,

I'd like to get a little more information regarding this ticket. Can you provide me some screen shots of your feed settings and other relevant screens.

Thanks,

What exactly do you need? For the record, I just tried to delete all feeds and recreate them from scratch and still get the same error.

Here's the error in the browser:
Since this is HTML, the nuget client complains about invalid XML:

My feed settings look like this:

The error is the same regardless of whether a connector to our previous Nuget server is configured or not.

Hi,

We are still discussing this issue internally. I am wondering if the issue could be with the endpoint.. can you change to /nuget/default instead of /feeds/default/nuget

Thanks,
Jason
