[error] [Window] TypeError: Cannot read properties of undefined (reading 'content')

When viewing/downloading a few >10 MB py notebooks I encountered the error above.
The smallest one caused the error is 10,929 KB, while a 7,230 KB one worked fine. I still need to test more to determine the exact size to cause the error.
The large size of these notebooks is mainly due to the output, so I can bypass it entirely by setting the Export Formats from .ipynb to .py. I haven't tested if a large notebook without the output would cause the same error.

Nvm I figure the cause.
The export API has a 10MB size limit.
If exceeded it throws an exception with error code MAX_NOTEBOOK_SIZE_EXCEEDED, but still uses 200 success code.
We might consider a more clear error message, and then prompt the user to download via webUI / clear output then download / switch to .py output format.
