I found this problem after conversion all urls in one of my projects to
modern named params.
I created custom URL Converter class and registered it in root url conf
I test my project code using py.test with enabled `doctest-modules`
option. With this option py.test imports all modules and search docstring
tests in each. Same happens with individual urls.py modules, but direct
module import fails with next stacktrace:
api/urls.py:86: in <module>
/usr/local/lib/python3.6/site-packages/django/urls/conf.py:70: in _path
pattern = Pattern(route, name=name, is_endpoint=True)
self.converters = _route_to_regex(str(route), is_endpoint)
"URL route '%s' uses invalid converter %s." % (original_route, e)
E django.core.exceptions.ImproperlyConfigured: URL route
'modules/<slug:slug>/<uid:uid>/' uses invalid converter 'uid'.
I'm not sure if this issue should be solved inside Django itself, but I
thought it would be helpful to report it.
The report doesn't help me understand the issue in much detail. Can you
debug it a bit further so we can understand what's going on (to help
decide how to proceed), or at least provide a minimal sample project so
that someone else can?
