Hi! I'm trying to use a notebook as a card with

metaflow-card-notebook==1.0.8

and

metaflow==2.12.25

When trying to connect everything together so that it works on AWS, it seems that there are two nested errors. • one during rendering of the card • one during the handling of the above rendering error I only get this information :

Card render failed with error :

Internal error

and I've tried to debug as much as I can (e.g. kernel name, check notebook path, first executing with papermill and then rendering, timeout), but I'm beginning to be out of ideas of what could be the problem. And here is the bottom of the stack trace:

Traceback (most recent call last):

File "/usr/src/app/metaflow/metaflow/_vendor/click/decorators.py", line 21, in new_func

return f(get_current_context(), args, kwargs)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

File "/usr/src/app/metaflow/metaflow/plugins/cards/card_cli.py", line 758, in create

rendered_content = _render_error_card(error_stack_trace)

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

File "/usr/src/app/metaflow/metaflow/plugins/cards/card_cli.py", line 755, in _render_error_card

).replace(mf_card.RELOAD_POLICY_TOKEN, token)

^^^^^^^

NameError: cannot access free variable 'mf_card' where it is not associated with a value in enclosing scope

I've used a basic flow and notebook from the metaflow-card-notebook repo.

can you share the full stack trace ?

thanks for your feedback ! I will try with the

save_errors

argument as soon as our metaflow is up and running again (some troubleshooting is happening right now). Here is the full stack trace

hey ! it seems like the version is older because we had patched this earlier, can you upgrade metaflow to latest version ? The latest package doesn't have this bug anymore.

strange because my docker image build log is showing that it is installing metaflow 2.12.25. Will have to check why this is not the actual version being used. Thanks for the feedback
