@SuperSandro2000 can you look at it?

[SuperSandro2000]

How can I tell jest to show me output of logger.debug?

[SuperSandro2000]

That repo so not visible for me. Can you paste the flake.nix and flake.lock with only the inputs that causes that error?

[szinn]

Sorry, repo is https://github.com/szinn/nix-config which is public

[SuperSandro2000]

The problem is that flake-parts uses a tarball download which the updater doesn't support https://github.com/hercules-ci/flake-parts/blob/32ea77a06711b758da0ad9bd6a844c5740a87abd/flake.nix#L5

Is there a reason why it doesn’t / can’t support it? Prior to that PR, it did

I can change the code so that the error is not generated but updates for that input are not possible as we don't know the branch the commit is from.

[szinn]

I think treating it as a warning rather than an error will restore the previous behavior.

[SuperSandro2000]

Before we didn't check the schema at all and it has so many optional fields that it is kinda hard to know which are not optional unless we would do some crazy validation logic.

Fixed with the second commit in #33991 with a new test case and also fixed an issue where nixpkgsRegex found a wrong version upgrade
