I have a script that:
1. Reads the layers in my Table of Contents
2. exports them to a feature dataset
3. re-adds the exported features
4. applies a pre-determined symbology to them based on layer files.
I've managed to complete steps 1 and 2, however, I am getting hung up with an Assertion Error at step 3.
My code is below. The error is arising in Section 3: RE-ADD NEWLY EXPORTED BASE FEATURES.
ArcMap is giving me the following error:

Does anyone have any idea what's going on here? Any help would be appreciated.
Thanks!
