server in an upstream can contain only host:port for a server, not an URI.

If you need to resolve server hostname in runtime, try this config:

resolver 10.0.0.8;

upstream backend {
zone z_backend 8k;
server backend.example.com resolve;
}

server {
location /foo/ {
proxy_pass http://backend/api/v2/;
}
}
