Flask route giving 404 with floating point numbers in the URL

I have the following route definition in my Flask app's server.py:

@app.route('/nearby/<float:lat>/<float:long>')
def nearby(lat, long):
    for truck in db.trucks.find({'loc': {'$near': [lat, long]}}).limit(5):
        if truck.has_key('loc'):
            del truck['loc']
    return json.dumps(trucks)

But when I go to http://localhost:5000/nearby/37.7909470419234/-122.398633589404, I get a 404.

The other routes work fine, so it's an issue with this one. What am I doing wrong here?

As of Werkzeug 0.15 the built-in float converter has a signed=True parameter, which you can use for this:

@app.route('/nearby/<float(signed=True):lat>/<float(signed=True):long>')
