About the nbdev category

Hi, I’m unable to create a post so I’m posting here. Is it possible to use nbdev.export in colab. I’m unable to use nbdev export:

nbdev.export.nb_export('app.ipynb', '.')

Getting following error:

JSONDecodeError: Expecting value: line 1 column 1

PS:
Just got the ability to post. I’ve posted the question here.
