It's difficult to find a bug if page has no stack trace or readable error.
I caught this error if I do not return anything from the context
processor. It would be great if Django will add a readable error for this
situation.
If you have a custom 404 template and page not found then you got 500
error without understanding why.
Reproducible application -

One more example of a context processor that can generate the same error:
{{{
def url_info(request):
"""
Adds url info.
"""
info = resolve(request.path_info) # raised exception for 404 page
return {
"url_info": {
"app_name": info.namespace,
"url_name": info.url_name,
"full_name": f"{info.namespace}:{info.url_name}"
}
}
}}}
