Getting a not found error on Flask routing?

Issue

I tried everything but the route just doesn't seem to work. I'm new to flask and I am running it locally. Also, my angular js code gives a 404 on posting the data to flask as the route doesn't seem to exist.

app.py

@app.route('/')
@app.route('/index')
def IndexPage():
    return render_template('index.html')

#these routes don't work although all of the others do which is very confusing
@app.route('/misc')
@app.route('/contact/mama')
def printHello():
    return render_template('index.html')


@app.route('/contact')
def ContactPage():
    return render_template('contact.html')


@app.route('/about')
def AboutPage():
    return render_template('about.html')


if __name__ == '__main__':
    app.run()

Here is my angular code and the python script trying to handle the post request

var formApp = angular.module('formController', []);
formApp.controller("formControl", function($scope,$http) {
    alert("mama");
    $scope.FormSubmit = function ()
    {
        alert("In the function");
        var data =
            {
            name : $scope.user.name,
            phone : $scope.user.phone,
            email : $scope.user.email,
            message : $scope.user.message
            };
        var result = $http.post('contact/userData', data, null);
        result.success(function(response)
        {
            const message = response.status;
            alert(message)
            alert("Thanks for contacting us");
        });
        result.error(function(data, status, headers, config)
        {
            console.log(result)
            alert("Error while submitting data");
        });
        $scope.user.name = '';
        $scope.user.phone = '';
        $scope.user.email = '';
        $scope.user.message = '';
    };
});

and here is the python script to handle the request

import sys import app import json from flask import request

@app.route("/contact/userData", methods=['GET','POST'])
def SendMail():
    message = json.dump({'status': 'success'})
    return message

Solution

json.dumps() was causing a problem. Changed it to jsonify method and the code started working.
