Why does my .wsgi file give me Internal Server Error?

Question

Apache 2.4 - RHEL 8.3 (Ootpa) - Windows

I have problems running the WSGI file on the server. Getting Internal Server Error. (I'm new at this)

I have installed the "python3-mod_wsgi" (as the mod_wsgi is said to not work with windows)

Checking if working:

root@xxx# sudo httpd -M | grep wsgi
proxy_uwsgi_module (shared)
wsgi_module (shared)

Which means it works(?)

I tested with the hello world (test_wsgi.py script) example:

def application(environ, start_response): status = '200 OK' output = 'Hello World!'
response_headers = [('Content-type', 'text/plain'),
                    ('Content-Length', str(len(output)))]
start_response(status, response_headers)

return [output]

Which worked:

My conf file: (edited out the /path/)

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        ServerName my.server.name
        DocumentRoot /path/api

        WSGIScriptAlias /lisens/test_wsgi /path/api/lisens/test_wsgi.py

        WSGIScriptAlias /lisens/hello_world /path/api/lisens/hello_world.wsgi

        <Directory/path/lisens>
                AllowOverride All
                Require all granted
        </Directory>

        Alias /static /path/lisensAPI/static>
        <Directory /path/lisens/lisensAPI/static/>
                AllowOverride All
                Require all granted
        </Directory>

        LogLevel info

</VirtualHost>

But when I try out the hello_world.wsgi:

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!\n'
    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)
    return [output]

I get Internal Server Error

I'm doing this test to later apply to my Flask application.

Any ideas? Please tell me if there is more information required to solve this.

Found the log. Apparently the string was wrong. added b'' in front.
