Trying to pickle (serialize into a storable format) an unplickable
object, such as a fuction.

what gets assigned to 'upload_file' is probably not pickleable.  What
that is I don't know, you will have to find out what kind of object is
getting assigned or is trying to store itself as a property.  This is
just a guess, there is not enough information to pin it down exactly.
