Paperspace Notebook Error

I have started the fastai course and completed the setup of the paperspace when I clicked on 01_introduction Notebook from jupyter-home page I get the following message on the pop-up

Notebook validation failed: Additional properties are not allowed (‘transient’ was unexpected):
“data”: {
“application/vnd.jupyter.widget-view+json”: {
“model_id”: “6518be5fb3794bfdad7a983209416d1d”,
“version_major”: 2,
“version_minor”: 0
“text/plain”: “FileUpload(value={}, description=‘Upload’)”
“metadata”: {},
“output_type”: “display_data”,
“transient”: {}

if I ignore above pop-up and go forward after running a couple of cells in the cell below the kernel dies and the is Notebook configuration error.
