Python Flask Basics Welcome to Flask Request args

non-200 response in Flask Basics challenge

My workspace code functions correctly but when I use the same code for the challenge I keep getting a non-200 response.

I can't spot why there's an error now but not before. Can anyone help point it out?

Previous code from workspace (for reference):

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/')
def index(name = "Treehouse"):
  name = request.args.get('name', name)
  return "Hello from {}".format(name)

app.run(debug=True, port=8000, host="0.0.0.0")
flask_app.py 
from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/')
def index(name):
    name = request.args.get('name', name)
    return 'Hello {}'.format(name)

Your dict.get fallback value seems like a strange choice here. Typically:

some_dict.get('key_name', 'default_backup') -- think about that maybe?

Compare your previous answer to your latest code. What happens when index() is called without an argument? What would be the value of name?
