Package resolution error

[keijiro]

Package Manager fails to import packages via the UnityNuGet registry with the following error message.

I tested with Unity 2019.4 and 2020.1 (reproduced on both of them).

You have to clear the local package cache to reproduce the issue.

Yeah, I haven't check the experience in the editor since it was launched, so UPM might require new/different fields from the package/JSON-request-result that it was not requiring before.

The strange thing is that I got the same inquiry from multiple users this week (I had never gotten one before). Did you change anything recently?

[xoofx]

The only PR merged recently that is related to changing something in the package is #12 but it's not related to this tarball field missing...
I would think that something has changed in UPM. I have identified for example that the field tarball is no longer under the field distribution but dist, so could it could just that. I will try to see if that fixes it.

Actually, the issue is on UnityNuGet side, a change of the underlying JSON serializer used by ASP.NET that I haven't noticed. Should be fixable soon.

This should be fixed by commit 59e685d
I just tested with UPM on a 2020.1.12f1 version and the packages are back in the UI.

And thanks for the report! My apology for the trouble, that was my mistake of upgrading to a newer version of ASP.NET that broke implicitly a few things.

[keijiro]

I verified that the issue was resolved. Thanks!
