Is this on the 7.2.5 version or on the develop branch version?

As of 7.2.5 you can only save PDF streams, and everything else throws an exception like this... It looks like you were trying to save a "reference" node, not a stream.

On the develop branch version this should be fixed and it should gray-out the option, if it doesn't support saving a particular node. And it also should allow to save PDF strings.
