MCMS 2002 : Getting “Unable to cast object of type

Getting “Unable to cast object of type to type” error message in client side import scirpt

The sdo package path has been specified as standard windows physical file format as “E:\folder\sdofilename.sdo”

The SDAPI import method reads the sdo file path and it process afterward. It’s expecting a path format that compatible with HttpWebResponse. When we use x:// notation, .net might interpret it as a FileWebResponse and that’s could be what causes the InvalidCastException.
