Classify land cover to measure shrinking lakes | ArcGIS API for Python | Esri Developer

The code extracting the sentinel fata in this tutorial is not working for me.

sentinel2016 = gis.content.get("a264d1eaa8bd4ff2a0a1e27b59daa7d3")

sentinel2017 = gis.content.get("ea192d03d1324c62a2cb91e26e3a0ece")

These Item IDs do not seem to be publicly accessible. Each of these have the following error traceback:

And the link to the Copernicus Open Access Hub via scihub.copernicus.eu also seems to be broken, so I do not know what data specifically needs to be downloaded for this training.

What could be the cause here? Many thanks!
