MCMS 2002 : Getting “Unable to cast object of type system.net.filewebresponse

  • Articolo

PROBLEM
========
Getting “Unable to cast object of type system.net.filewebresponse to type system.net.httpwebresponse” error message in client side import scirpt

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

ROOTCAUSE
==========
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.
