If you create a notebook “From URL“, the URL must return content in the Jupyter Notebook Format. The URL you shared returns HTML data.

If your Watson Studio instance runs in Tokyo (seen by jp-tok in the URL), you can add the notebook to your project via two different ways

• use the “Copy to project” button in the upper right corner
• use the “Download” button in the upper right corner and create the notebook from file

If your Watson Studio instance does not run in Tokyo and you cannot get access to the “Copy to project” or “Download” functionality, ask your course instructors to provide the notebook in a different way (e.g. via a .ipynb file).
