Laravel Livewire - 502 Bad Gateway

Question

I am using Laravel Valet in my development environment and I came across this error today when sending a post request with Livewire.

~/.config/valet/Log/nginx-error.log:

2020/05/17 10:44:27 [error] 3611#0: *1 upstream sent too big header while reading response header from upstream, client: 127.0.0.1, server: , request: "POST /livewire/message/autocomplete.users HTTP/1.1", upstream: "fastcgi://unix:/Users/macuser/.config/valet/valet.sock:", host: "blog.test", referrer: "http://blog.test/dashboard"

To fix it, change the following config files in your environment:

Create file ~/.config/valet/Nginx/all.conf

proxy_buffer_size   4096k;
proxy_buffers   128 4096k;
proxy_busy_buffers_size   4096k;

Append to file /usr/local/etc/nginx/fastcgi_params

fastcgi_buffer_size 4096k;
fastcgi_buffers 128 4096k;
fastcgi_busy_buffers_size 4096k;

After that, valet restart.
