Flask Windows Apache issues

I'm attempting to get Flask running off apache on windows and I'm coming across the error message below. Any ideas on what could be causing this issue?

Error Message:

my WSGI file looks like this:

import sys
sys.path.insert(0, "c:\i4\importicus")

from importicus import importicus_main as application
application.debug = True

and my application file looks like this:

from flask import Flask, render_template,jsonify, request
from werkzeug import secure_filename
import importicus_functions
import ast, os, sys
importicus_main = Flask(__name__)

UPLOAD_FOLDER = 'uploads'
TEMPLATE_FOLDER = 'templates'
importicus_main.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
importicus_main.config['TEMPLATE_FOLDER'] = TEMPLATE_FOLDER



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

The main problem is you're trying to write WSGI, not Flask. (Flask is WAY easier.)

This is what you want:

@importicus_main.route('/')
def application():
  return "Hello World! INSIDE"

Controllers (like the application function) don't take parameters, unless there are parameters in your url string. An example would be:

# /blog/1 would be a valid URL here
@importicus_main.route('/blog/<int:post_id>')
def blog_post(post_id):
  return "This would be blog post number %s" % post_id

Take a look at the Flask tutorial if you skipped it - it's excellent. I'd also suggest getting your app running with the built-in test server. You can easily port to mod_wsgi (or whatever) later.
