I'm using AWS ELB to deploy flask backend api. I have an endpoint that uploads a file and another endpoint that reads data from the file.
Every other endpoint works fine but when I run the endpoint that reads data the file that was uploaded it runs for about 30 seconds and it throws the 502 bad gateway error.
ELB error: 2022/03/08 17:30:19 [error] 25807#25807: *25 upstream prematurely closed connection while reading response header from upstream, client: 172.31.0.71,

I have tried a whole lot of answers but none has worked for me. Please I need help
