The same issue after upgrade from 2.11.11 to 3.0.4.

[eudjinnl]

Thank you for your participation. It looks like you are more profficient than me in issues like this

[candlerb]

To summarise: this is issue #7401 which was worked around in Netbox v3.0.5. So the answer is simply to update to v3.0.5 or v3.0.6.

[candlerb]

Something went wrong in your upgrade, but without more details I can't tell what it is. There are two places you should look for error messages:

1. At the backend: try journalctl -eu netbox
2. Open your browser's developer console, then fetch the documentation again. You should be able to see the response code and/or the response body in the 'Network' or 'Console' tabs. I'm guessing it's a code 500 ('internal server error') but maybe the body has some more details.

The other thing you should do is to set ADMINS and EMAIL in configuration.py (and restart netbox). Then if an exception occurs server-side, you should get a full backtrace mailed to you. Paste it here and we should be able to help you interpret it.

Server Error
A module import error occurred during this request. Common causes include the following:

Missing required packages - This installation of NetBox might be missing one or more required Python packages. These packages are listed in requirements.txt and local_requirements.txt, and are normally installed as part of the installation or upgrade process. To verify installed packages, run pip freeze from the console and compare the output to the list of required packages.

WSGI service not restarted after upgrade - If this installation has recently been upgraded, check that the WSGI service (e.g. gunicorn or uWSGI) has been restarted. This ensures that the new code is running.

The complete exception is provided below:

<class 'ModuleNotFoundError'>

No module named 'jsonschema.compat'

Python version: 3.8.6
NetBox version: 3.0.4
If further assistance is required, please post to the NetBox discussion forum on GitHub.

Can you recommend how to install the missing module (No module named 'jsonschema.compat')?

This is starting to look like a problem with a plugin. Can you comment out your plugins in configuration.py and repeat?

Aha. Inside my virtualenv, pip freeze shows:

jsonschema==3.2.0
...
swagger-spec-validator==2.7.3

whereas yours shows:

jsonschema==4.0.1
...
swagger-spec-validator==2.7.3

I see that at the end of my requirements.txt I have:

# Workaround for #7401
jsonschema==3.2.0

This was added in commit 114500e on 30 Sep 2021, which made it into netbox v3.0.5

So the answer is trivial: update to 3.0.5 (or 3.0.6 since that's out now). Phew!

[eudjinnl]

I've just updated to 3.0.6 - API documents open now.

Thank you, everybody, for helping me

[eudjinnl]

Thank you all! update to 3.0.6 hepls

[romanstech]

Confirmed. After upgrade to v.3.0.6 /api/docs/ works.
Thanks Brian for the quick help!

[eudjinnl]

Thank you once again for answering Brian's questions, it really hepls!
