Pynq Z2 import .IPNYB file issues

Hello, I am attempting to import a .ipynb notebook to my jupyter notebooks and am getting an error. It states that the file is an “invalid Notebook”. The image below shows the error and the filename. The git repository that I am pulling this .ipynb file from states that it is a notebook for a pynq-Z2 board which is what I am using.
Any advice? Thanks in advance

We have not tested that upload button and I think the best way to transfer file is through Samba / winscp or similar. Can you try that?
