Formgrader/Manual Grading fails to resolve past notebook ID

OS: Ubuntu 18.04 on Jetstream-cloud.org

nbgrader --version Python version 3.6.7 | packaged by conda-forge | (default, Feb 28 2019, 09:07:38)

[GCC 7.3.0] nbgrader version 0.5.5

jupyter --version 4.4.0 (The littlest JupyterHub)

(Partial) pip list jupyter 1.0.0 jupyter-client 5.2.4 jupyter-console 5.2.0 jupyter-core 4.4.0 jupyterhub 1.0.0 jupyterlab 0.35.4 jupyterlab-server 0.2.0 … nbconvert 5.5.0 nbformat 4.4.0 nbgitpuller 0.6.1 nbgrader 0.5.5 nbresuse 0.3.0 notebook 5.7.8 nteract-on-jupyter 2.0.7

jupyter notebook --version 5.7.8

Expected behavior

When opening nbgrader-> Manual Grading. I choose the Assignment ID -> Notebook ID -> view the scores for that notebook

Actual behavior

The browser just hangs here:

Steps to reproduce the behavior

these are the instructions I used to setup The Littlest Jupyter Hub: https://tljh.jupyter.org/en/latest/install/jetstream.html and then I used these instructions to install nbgrader: https://nbgrader.readthedocs.io/en/stable/user_guide/installation.html

I believe I have the proper folder structure with the exception of the “source” and “PrgPrin101” folder the other files and folders are created through nbgrader.

All nb/serverextensions are enabled.

the strange thing is if I go through Nbgrader/Formgrader/Manage Students I can see the assignment and grade it. the link in the right browser leads me to the actual assignment

nbgrader autograde was executed with each assignment. any help would be greatly appreciated

cheers,
