I am trying to convert a 32-bit floating point raster with 205289 columns and 120615 rows to a polygon using Raster Domain. It creates a feature class that does not contain any polygon. There is a record in the attribute table but it says zero in the Shape_Length and Shape_Area fields.

Any ideas why I am getting this output? Or other suggestions how to convert this raster to a polygon? I just need a simple polygon to delineate the boundary of my raster.
