My app is throwing ERROR 500 while accessing example.com/sitemap.xml Additional server configurations = Nginx+Gunicorn+postgres

Here are my files

from .models import Post, Status 

class PostSitemap(Sitemap):    
    changefreq = 'daily'
    priority = 0.9

    def items(self):
        return Post.objects.filter(status=0)

    def lastmod(self, obj):
        return obj.created_on

class StatusSitemap(Sitemap):
    changefreq='daily'
    priority = 0.9

    def item(self):
        return Status.objects.filter(status=0)

    def lastmod(self, obj):

url.py

sitemaps = {
    'posts': PostSitemap,
