010421: Invalid environment object or its settings.

Description

An error occurred during analysis where an invalid environment value is causing the process to fail.

This could happen during a conversion from feature class to raster, or when using a feature class input as a mask. Possibly, the output extent is not compatible with the specific cell size.

Solution
