XArrrayToRaster fails with projection error

I'm using ArcGIS Pro 3.0.3.

I'm doing some raster processing where I need functionality that the Arcgis tools don't provide. The data is a multidimensional raster. I thought XArray would be a good way to handle this. The conversion from raster to xarray worked fine. The xarray processing produced the desired results. The conversion back to raster is failing with a message about projection. To test things out I tried a simple in and out on the same data which failed.

import arcpy temp_max_file = r"D:\r3_analyst_work\Climate_Change_Modeling\climate_envelope\GridMetData_2020\tmmx_2020.nc" test_rast = arcpy.Raster(temp_max_file,True) test_rast_xr = arcpy.ia.RasterToXarray(test_rast) out_rast = arcpy.ia.XarrayToRaster(test_rast_xr)

This produces the following message:

---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)
