Difficulty running invoke update due to (corsheaders.E014) error.

[siegfriedclarke]

Hello All,

I seem to have hit some difficulty running invoke update on my bare metal install.

The first tests against requirements.txt seem to pass but then I get the following error.

/opt/inventree/env/lib/python3.9/site-packages/allauth/exceptions.py:9: UserWarning: allauth.exceptions is deprecated, use allauth.core.exceptions
  warnings.warn("allauth.exceptions is deprecated, use allauth.core.exceptions")
SystemCheckError: System check identified some issues:

ERRORS:
?: (corsheaders.E014) Origin 'https://inventree.serverurl.co.uk/' in CORS_ALLOWED_ORIGINS should not have path
Python version 3.9.5 - /opt/inventree/env/bin/python3
ERROR: InvenTree command failed: 'python3 manage.py collectplugins'
- Refer to the error messages in the log above for more information

The part that I'm getting especially confused by is that the origin https://inventree.serverurl.co.uk/ is not set at all in the relevant config file, which currently has base_url commented out and the CORS settings as follows:

# Cross Origin Resource Sharing (CORS) settings (see https://github.com/ottoyiu/django-cors-headers)
# Following parameters are
cors:
  # CORS_ORIGIN_ALLOW_ALL - If True, the whitelist will not be used and all origins will be accepted.
  allow_all: true

  # CORS_ORIGIN_WHITELIST - A list of origins that are authorized to make cross-site HTTP requests. Defaults to []
  # whitelist:
  # - http://inventree.serverurl.co.uk
  # - https://sub.example.com

The issue seems to be the trailing '/' in the origin, which from what I can tell is a pretty common django issue but I cannot figure out how to resolve this. Any ideas?

Looks like the trailing slash is the issue - https://stackoverflow.com/questions/56404930/when-trying-set-corsheaders-in-settings-py-file

Where is the URL coming from, your config file (config.yaml) or from your environment variables?

[siegfriedclarke]

This is the bit that is confusing me. The url does not appear to be referenced in config.yaml nor is it referenced in any active environment variable.

[SchrodingersGat]

It has to be coming from somewhere! What setup are you using?

• Docker
• Installer
• bare metal

[siegfriedclarke]

For completeness - I believe this install was done with the early one line installer, running on Ubuntu 20.04.06

@siegfriedclarke I can reproduce the bug in any case - fix is incoming in #9559

Thanks so much for the quick fix! Absolutely love what you're doing with Inventree.
