Hello All,
I am trying to publish my third notebook and it is failing with this exception:

The whole notebook is running fine with no exceptions.
Has anyone of you ever encountered such problem?
I have already raised an issue with the Kaggle team but decided to ask here as well.
Might help others in future.
Thanks in advance
