The upstream CI has been failing for a while. Here's the latest:
https://github.com/pydata/xarray/actions/runs/5501368493/jobs/10024902009#step:7:16

```python

Digging a little in the logs

Might be some numpy problem?

Should the CI be robust enough to handle these kinds of errors? Because I suppose we would like to get the automatic issue created anyway?","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/7969/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed,13221727,issue
