See https://buildkite.com/clima/climaatmos-ci/builds/27628#019bca5b-6ae8-4ad8-a8e0-63e4014470c5. I'll mark it as soft-fail now. @nefrathenrici could you look at it?

Looks like it's random, as it works in this build: https://buildkite.com/clima/climaatmos-ci/builds/27638#019bce46-d674-47d8-ae8a-fb85c27c33d0. Maybe we can remove the soft fail if it works for a couple more builds.
