Formgrader doesn't work, command line do

[bpfrd]

Hi
I deployed jupyterhub & nbgrader in kubernetes. I'm using this version of nbgrader https://github.com/CERIT-SC/nbgrader-k8s
please find the issue and details below:

Operating system

Centos

nbgrader --version

nbgrader version 0.9.2

jupyterhub --version (if used with JupyterHub)

jupyterhub version 3.0.3

jupyter notebook --version

jupyterhub notebook version 7.1.2

Actual behavior

Formgrader stopped working recently and none of its functionalities, e.g., autograde, release feedback, manual grading, etc work! It doesn't give any specific errors. it shows something like "there is an error in autograding...." However, the command line works. but manual grading is not possible with the command line.

best regards

I should add that, when doing manual grading the comments and grades are not saved and have no effect.

@bpfrd did you update nbgrader or jupyterlab/notebook recently ?
Otherwise, I would suspect an issue with configuration, maybe related to https://github.com/CERIT-SC/nbgrader-k8s (I don't know about that).

Thanks. I didn't update and I don't think teachers did too. How can I debug?
We do autograding, releasing assignment, etc. with command line. Is it possible to do manual grading with command line as well?

For reference CERIT-SC/nbgrader-k8s#11

Manual grading from the command-line would need an alternative UI to allow comments & grade-changes - which seems a lot of work when there's already a UI available
