I am trying to get this zip file I generated to update data -> append data to layer. If I manually download the zip file I generated and manually go in and append data to layer it works exactly how I want it. The problem is my python code, which I admit I am new to.

I want to make sure I am appending data to my layer aka doing what I did manually on python. I tried to code based on a tutorial I watched and I am getting an error which I cannot figure out. I am not sure if what I have would completely replace the layer or just add new data (which is what I am trying to accomplish)

Attached is my code with a photo of the error I get:
