'ellipsis' object has no attribute 'lower'

[Bharath_AK]

Hi There,

I am getting the following error when I run python3 manage.py runserver 0.0.0.0:8000

Error:
File "/usr/local/lib/python3.6/dist-packages/django/core/handlers/exception.py", line 41, in inner
    response = get_response(request)
  File "/usr/local/lib/python3.6/dist-packages/django/utils/deprecation.py", line 138, in __call__

  File "/usr/local/lib/python3.6/dist-packages/django/utils/http.py", line 291, in is_same_domain
    pattern = pattern.lower()
AttributeError: 'ellipsis' object has no attribute 'lower'

I am running this command on ubuntu 16.04 in aws.

Please help me how to fix this error.

With Many thanks,

The object ellipsis is represented by ... three dots.
This object is used somewhere as slice notation for scientific libraries like numpy.

If you put somewhere in you django config three dots without quotes,
it's recognized as a valid object, but it is in this case not a string.

Look for three dots in your config, edit it and then you'll be able to run it.

You can perhaps find the file with the command

Output:
grep -E -e "[.]{3}" -r /your/project/folder
