Django and React the dashboard is empty

i am doing the project in grafana i have done docker’s. in that we are having prometheus.yml file. we also have Docker compose.yml file and we have modify it according to prometheus.yml file.
and when we search (localhost:9090/target) in this url our all exporter status is “up”.
and my project is also working fine, in grafana i have also tested pg_up query and nginx_up query this is working fine, we can see it in dashboard.
problem:
there is no react file in dashboard
Nginx (React)
nginx_react_connections_total
nginx_react_http_requests_total
and no Django file in dashboard
Django
django_http_requests_total
django_db_connections_total
django_cache_hits_total
and when i print the logs i can’t see any errors though this react and django file is not shown in dashboard can you give me the proper detailed way to overcome this problem?
nginx_react_up.

In ANY EXPORTER OR MY PROJECT IN DOCKER HAS NO LOGS AS I HAVE SHOWN YOU IN THE SCREENSHOT.

help me to troubleshoot this issue systematically.
