Internal Server Error when running JupyterHub cell

[Dagim Mindaye]

Hello, I’m getting this error when running the configuration cell in JupyterHub (see the code and the error below):

from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager

project_id = “5c7270ea-dea3-4388-bad0-c8c4fb9a2c96”

fablib = fablib_manager(project_id=project_id)

During handling of the above exception, another exception occurred:

Hi Dagim,

Thank you for sharing this observation. Could you update the instantiation of the fablib object in the first cell to the following and then try running the notebook again?

fablib = fablib_manager(project_id=project_id, validate_config=False)

Thanks,
Komal

Thank you so much. The issue has been resolved. The old code cell now works but I’ll be sure to use this if I get the same error again.
