Allowing post request through Nginx - django

Question

Trying to serve a react app, django with nginx and docker. I am not able to make a post call from docker on port 8080 to nginx on port 8082.
Following is the error thrown by Nginx
iris-frontend-frontend-1 | 2022/10/13 20:16:18 [error] 35#35: *4 open()
"/usr/share/nginx/html/add-to-waiting" failed (2: No such file or directory), client:
172.18.0.1, server: localhost, request: "POST /add-to-waiting HTTP/1.1", host:
"localhost:8080", referrer: "http://localhost:8080/"
Nginx configurations are:
add-to-waiting is the api call.
upstream django {
server website:8000;
}
upstream react_app {
server frontend:8080;
}
server {
listen 80;
client_max_body_size 100M;
proxy_set_header X-Forwarded-Proto $scheme;
location / {
proxy_pass http://react_app;
}
location /admin {
proxy_pass http://django;
}
location /add-to-waiting {
proxy_pass http://django;
}
location /media/ {
alias /app/media/;
}
location /static/ {
alias /app/forex/static/admin/;
}
}
What configurations need to change to make frontend able to call the api?
