I'm using Django with FastCGI + nginx. Where are the logs (errors) stored in this case?

Errors are stored in the nginx log file. You can specify it in the root of the nginx configuration file:
error_log /var/log/nginx/nginx_error.log warn;
On Mac OS X with Homebrew, the log file was found by default at the following location:
/usr/local/var/log/nginx

That's maybe version dependent but my log is inside:
/opt/nginx/logs/error.log

on Mac OS X with homebrew: /usr/local/var/log/nginx. see lfender's answer

On ubuntu I have it in
/var/log/nginx/error.log. It is best to check the nginx.conf file and find the error_log setting.

Found mine at /opt/homebrew/var/log/nginx/error.log lol. Currently on macOS 13 (Ventura). Also seems you could run
nginx -h to view the default log output directory.

For MacOS / homebrew install, run
nginx -t to output the location of your nginx.conf. Go to the parent folder and you can find your logs folder there.I was looking for a different solution.
Error logs, by default, before any configuration is set, on my system (x86 Arch Linux), was found in:
/var/log/nginx/error.log

Apparently this is configureable only at compile time with the
--error-log-path compile option trac.nginx.org/nginx/ticket/147

on raspberry pi3 its the location
You can use lsof (list of open files) in most cases to find open log files without knowing the configuration.
Example:
Find the PID of httpd (the same concept applies for nginx and other programs):
$ ps aux | grep httpd
...
root 17970 0.0 0.3 495964 64388 ? Ssl Oct29 3:45 /usr/sbin/httpd
...
Then search for open log files using lsof with the PID:
$ lsof -p 17970 | grep log
httpd 17970 root 2w REG 253,15 2278 6723 /var/log/httpd/error_log
httpd 17970 root 12w REG 253,15 0 1387 /var/log/httpd/access_log
If lsof prints nothing, even though you expected the log files to be found, issue the same command using sudo.
You can read a little more here.

it's a nice trick to remember.. no guessing any more where the log files could be

+1 For an answer on how to look. I was looking for logs from a different installation of nginx and it wasn't in the top answer.

you can poke at similar data on linux in the
/proc filesystem. /proc/${pid}/fd has symlinks to the open files, pipes, devices, etc

while using [$ ps aux | grep httpd] I got =auto httpd (in red). do you know what it means please?

Run this command, to check error logs:
tail -f /var/log/nginx/error.log

My ngninx logs are located here:
/usr/local/var/log/nginx/*
You can also check your nginx.conf to see if you have any directives dumping to custom log.
run nginx -t to locate your nginx.conf.
# in ngingx.conf
error_log /usr/local/var/log/nginx/error.log;
error_log /usr/local/var/log/nginx/error.log notice;
error_log /usr/local/var/log/nginx/error.log info;
Nginx is usually set up in /usr/local or /etc/. The server could be configured to dump logs to /var/log as well.
If you have an alternate location for your nginx install and all else fails, you could use the find command to locate your file of choice.
find /usr/ -path "*/nginx/*" -type f -name '*.log', where /usr/ is the folder you wish to start searching from.

The logs will be here if you installed Nginx with Homebrew.
Logs location on Linux servers:
Apache – /var/log/httpd/
IIS – C:\inetpub\wwwroot\
Node.js – /var/log/nodejs/
nginx – /var/log/nginx/
Passenger – /var/app/support/logs/
Puma – /var/log/puma/
Python – /opt/python/log/
Tomcat – /var/log/tomcat8

For Mac OS users, you can type nginx -help in your terminal.
nginx version: nginx/1.21.0
Usage: nginx [-?hvVtTq] [-s signal] [-p prefix]
[-e filename] [-c filename] [-g directives]
Options:
-?,-h : this help
-v : show version and exit
-V : show version and configure options then exit
-t : test configuration and exit
-T : test configuration, dump it and exit
-q : suppress non-error messages during configuration testing
-s signal : send signal to a master process: stop, quit, reopen, reload
-p prefix : set prefix path (default: /opt/homebrew/Cellar/nginx/1.21.0/)
-e filename : set error log file (default: /opt/homebrew/var/log/nginx/error.log)
-c filename : set configuration file (default: /opt/homebrew/etc/nginx/nginx.conf)
-g directives : set global directives out of configuration file
Then, you could find some default path for configuration and log files, in this case:
/opt/homebrew/log/nginx/error.log

why is this different for different users? For me it is in
opt/homebrew/var/log/nginx/error.log. Doesnt make any senseType this command in the terminal:
sudo cat /var/log/nginx/error.log

That is not an answer and should be a comment instead. Once you have sufficient reputation you will be able to comment.
cd /var/log/nginx/
cat error.log

It is a good practice to set where the access log should be in nginx configuring file . Using acces_log /path/ Like this.
keyval $remote_addr:$http_user_agent $seen zone=clients;
server { listen 443 ssl;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
if ($seen = "") {
set $seen 1;
set $logme 1;
}
access_log /tmp/sslparams.log sslparams if=$logme;
error_log /pathtolog/error.log;
# ...
}
