AssertionError: assert self.before.build is not None

I suspect this might be due to the recent upgrade to lockfile format v6?

update.json

wtf I just ran into this too!

I have a JSON diff where the structure is

{
  "version": 1,
  "environment": {
    "default": {
      "linux-64": [
        {
          "name": "pkg",
          "before": {
            "conda": "https://artifactory.corp.com/artifactory/conda/noarch/pkg-0.23.0-gcc70d65.conda"
          },
          "after": {
            "conda": "https://conda.registry.hosted.com/prod/noarch/pkg-0.23.0-gcc70d65.conda"
          },
          "type": "conda",
          "explicit": true
        }
      ]
    }
  }
}

I got this by removing a channel override and so it makes sense, the build didn't change, just the URL

Workaround: downgrade pixi to v0.38.0. If you're using GHA, this is:

      uses: prefix-dev/setup-pixi@v0.8.1
      with:
        pixi-version: v0.38.0

This prevents a lockfile format change.

It seems to be not just the transitional diff that's broken. It seems that there was a schema change in the diff, corresponding to a lockfile version change. So unless I'm mistaken, this is simply broken for pixi v0.39.0.
