Fix MalformedTrailerError

in NGINX

Solution

MalformedTrailerError in Nginx usually arises when the upstream server sends chunked responses with incorrect or missing trailers after the last chunk. To fix this, try disabling response buffering in Nginx using `proxy_buffering off;` along with `proxy_request_buffering off;` in your Nginx configuration for the specific location or server block to ensure trailers are passed correctly. If this doesn't work, investigate and fix the upstream server's chunked encoding implementation.
