502 Bad Gateway on firstOrCreate

Posted 3 months ago by chimit

I made a trivial code change in my project and PHP 7.3 starts crashing after it.



            $user = User::whereUid($token_payload->user_id)->first();

            if ($user === null) {
                $user = User::create([
                    'uid' => $token_payload->user_id,
                    'email' => $token_payload->email ?? null,


            $user = User::firstOrCreate([
                'uid' => $token_payload->user_id
            ], [
                'email' => $token_payload->email ?? null,

After a couple of minutes after pulling this commit PHP crashes and I get "502 Bad Gateway" from nginx.

MySQL requests generated by these two pieces of code are the same.

There is nothing in Laravel or nginx logs.

PHP 7.3 logs:

If I revert this commit and restart php-fpm everything works smoothly again.

P.S. It's a Laravel Forge server.
