Cannot read property 'name' of undefined.

I download my ipynb from https://colab.research.google.com/notebooks/welcome.ipynb. When i open it in vscode, it inform me that TypeError: Cannot read property 'name' of undefined. But there is no problem when i open it in jupyter notebook.
Thanks.

The same problem with some notebooks.

I haven't got a chance to take a look at this. I will give a status update by the next release

I have same issue, it repeats every time:
Using MagicPython language:

• I click on jupyter file, i.e. ClassificationDemo-Python.ipynb, to open it in VSCode, in editor command 'extension.showPreview' not found #1 (left one)
• I click 'Show preview', and VSCode opens a preview, no problemo; I can view it in another editor (Default Preview View #2, right one)
• I have another python file opened in editor Default Preview View #2, and when I switch focus on this file, and then back to preview in editor Default Preview View #2, I get an error message - 'Unable to open 'IPython Notebook Preview': Cannot read property 'document' of undefined.'
  So, while switching (cursor focus) between
  ClassificationDemo-Python.ipynb
  and
  ClassificationDemo-Python.ipynb preview,
  there are no problems. When focus is on another file, and back to preview, error appears.
