Hi all!
I'm using Arcgis Notebooks in order to update some tables that I have published in portal.
the script takes a xls file, then It cleans a little bit the data and then it edits the table in the service.
That script is going to be used for other users, so I would like to include the option, when they want to run the Notebook, they could select the xls file.
So I was trying to use File Upload() widget from ipywidgets library but when I select the file to be uploaded, a message appers that says : Notebook Disconnected, Your active notebook session has lost connectivity unexpectedly (image below) btw, sorry all portal is in Spanish

The lines that I'm running:

I am not a full-time developer but I like to automate processes and ArcGIS Notebooks seem pretty good for that purpose
I appreciate any suggestions, thank you!
