[Scons-users] Errors in parallel builds after updating from SCons 2.3.0 -> 2.3.5

Your target node for the Command is None.
That's likely your issue. You're specifying None as a Node object.

You should likely use Value(None) or something like that.
Search for "Value(" in http://scons.org/doc/production/HTML/scons-man.html
