This is a known incompatibility between xarray and rasterio 1.0.14. I've already made the PR for xarray and it has been merged. Waiting on release I guess. I'm on mobile now so can't easily find the URL, sorry.

Found thanks: pydata/xarray#2715

I think this has been fixed for a long time. Going to close this. Let me know if you still see this exact issue.
