010045 : COSTPATH: The number of FROM cells is 0.

Description

The input that identifies those cells from which the least-cost path is determined does not contain any valid values. If the input is a raster, it should consist of cells that have valid values (zero is a valid value), and the remaining cells must be assigned NoData.

Solution

Ensure that the raster you specify as the destination dataset has some cells with a valid value (not NoData). Check the documentation for Cost Path for further information.
