TraitError when attempting to convert ipynb to confluence page

[boleszek]

I'm having trouble using this package because of a traitlets.traitlets.TraitError which I can't fix. I have already installed the relevant packages, created an Atlassian API key, set CONFLUENCE_USERNAME & CONFLUENCE_PASSWORD environment variables, and created a blank Atlassian webpage.

My command is

nbconflux "/Users/bo.osinski/Documents/imaging-research/bo/fragment-analyzer/fragmentation_data_EDA.ipynb" "https://tempuslabs.atlassian.net/wiki/spaces/TEM/pages/2021654744/Predicting+QC2"

And the error is

Using credentials for bo.osinski@tempus.com from environment variables
Traceback (most recent call last):
  File "/Users/bo.osinski/miniconda3/envs/nbconflux_conda/lib/python3.6/site-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'exporter'

During handling of the above exception, another exception occurred:

I've tried running this in my native python as well as a new python 3.6 conda environment, but always get the same TraitError. Does anybody have an idea how I can fix this? Thank you!

Unfortunately no. I've tried different versions of nbconflux, but always getting the same error.

The problem occurs because nbconvert 6 actually breaks nbconflux. This is my attempt to fix the problem https://github.com/criteo-forks/nbconflux/pull/2
