rio.write_crs returns 0 for spatial_ref

Following @snowman2 recommendation here, the rio.write_crs gave 0 for spatial_ref (see the attached screenshot) on my data. I was wondering what does 0 means in this context, is this the expected result?

This should help clarify: https://corteva.github.io/rioxarray/stable/getting_started/crs_management.html

Note: CRS information is stored in spatial_ref.attrs

Thanks for the clarification.
