How to send images from the Nginx server to the client?

Question

Nginx

A React project (client) and Express.js api are running on a dedicated server.

Implemented via proxy_pass, everything works.

Api implements the loading of images along the path /api/tmp.
Express has static handling of this folder enabled.

The problem is, nginx doesn't return images if I go to domain.ru/api/tmp.

Answer 1

1. paste the code as text, not as an image
2. read the error log from nginx

Answer 2

See how I did it, by the way, look for my question about nginx, it describes how to make a structure, the controller itself either gives the full path to the nginx location, or if this dynamic redirects to the same picture, as a result, everyone does their own thing, in general, the api distributes pictures and does not know where they are stored and nginx returns the static and caches it
