Bummer! Didn't get a 200 at /multiply ERROR

Not sure what this means. I feel like I have completed the instructions per the examples in the videos, but this is not passing for some reason. I've tried returning just the value as a string '25' and the formatted string with the equation. Same result for each.

flask_app.py
from flask import Flask

app = Flask(__name__)

@app.route('/multiply/<int:num1>/<int:num2>')
def multiply(num1, num2):
    # return str(num1 * num2)
    return '{} * {} = {}'.format(num1, num2, num1 * num2)

Hi jonlunsford

Make sure you are allowing for floats and integers to be passed to the route. Also you have not supplied default parameters to the passed in the arguments in the function multiply. See my code below which passes the challenge.

@app.route('/multiply')
@app.route('/multiply/<int:num1>/<int:num2>')
@app.route('/multiply/<int:num1>/<float:num2>')
@app.route('/multiply/<float:num1>/<int:num2>')
@app.route('/multiply/<float:num1>/<float:num2>')
def multiply(num1=5,num2=5):
    return str(num1 * num2)

Thank you Andreas for your help with this. I had not considered passing in the default values.
