413 Request Entity Too Large — Nginx Request Too Large

Что вызывает эту ошибку

The client sent a request body larger than the client_max_body_size setting (default 1 MB).

Как исправить

Increase client_max_body_size in the nginx.conf or server block. Add client_max_body_size 100m; for 100 MB uploads.

# In nginx.conf
http {
  client_max_body_size 100M;
}
