My Reset password link for my flask web app is not redirecting and updating the password

Question

So I have this function to reset the user password through email, everything works fine (Almost) The email is send with the token and I am able to open the link which redirects me to the page to type in my new password, but when I do and submit. It redirects me to a 404 page I created to go to when the user tries to go to an incorect page

Here is my relevant code

def send_reset_email(user):
    token = user.get_reset_token().decode('utf-8')  # Decode bytes to string
    print("Reset Token:", token)
    msg = Message('Password Reset Request', sender='[email protected]', recipients=[user.email])
    msg.body = f'''
    To reset your password, visit the following link:
    {url_for('reset_token', token=token, _external=True)}

    If you did not make this request, please ignore this email and consider changing your email and password.
    '''
    mail.send(msg)

@app.route("/reset_password", methods=['GET', 'POST'])
def reset_request():
    if current_user.is_authenticated:
        return redirect(url_for('index'))
    form = RequestResetForm()
    if form.validate_on_submit():
        user = User.query.filter_by(email=form.email.data).first()
        send_reset_email(user)
        flash('Reset password email has been send', 'info')
        return redirect(url_for('signin'))
    return render_template('reset_request.html', title='Reset Password', form=form)

@app.route("/reset_password/<token>", methods=['GET', 'POST'])
def reset_token(token):
    print( url_for('signin') )
    print("Reset Token Route Triggered")
    if current_user.is_authenticated:
        print('redirecting you to index')
        return redirect(url_for('index'))
    user = User.verify_reset_token(token)
    if user is None:
        print('The user value was none')
        flash('That is an invalid or expired token', 'warning')
        return redirect(url_for('reset_request'))
    form = ResetPasswordForm()
    if form.validate_on_submit():
        hashed_password = bcrypt.generate_password_hash(form.password.data).decode('utf-8')
        user.password = hashed_password
        print(f"new password is {user.password}")
        db.session.commit()
        print("Password has been committed")
        flash(f'Your password has been updated', 'success')
        print("Redirecting you now to sign in")
        return redirect(url_for('signin'))
    return render_template('reset_token.html', title='Reset Password', form=form)

User Model

class User(db.Model, UserMixin):
    # Manual Table name choice
    __tablename__ = 'users'

    id = db.Column(db.Integer, primary_key=True)
    firstname = db.Column(db.String(100), nullable=False)
    lastname = db.Column(db.String(100), nullable=False)
    email = db.Column(db.String(100), unique=True, nullable=False, index=True)
    password = db.Column(db.String(130), nullable=False)

    def get_reset_token(self, expires_sec=1800):
        s = Serializer(app.config['SECRET_KEY'])
        return s.dumps({'user_id': self.id}).encode('utf-8')

    @staticmethod
    def verify_reset_token(token):
        s = Serializer(app.config['SECRET_KEY'])
        try:
            user_id = s.loads(token)['user_id']
        except:
            return None
        return User.query.get(user_id)

    def __init__(self,firstname,lastname,email,password):
        self.firstname = firstname
        self.lastname = lastname
        self.email = email
        self.password = password

and finally my fors to reset password and request reset form

class RequestResetForm(FlaskForm):
    email = StringField('Email', validators=[InputRequired(), Email()])
    submit = SubmitField('Request Password Reset')

    def validate_email(self, email):
        user = User.query.filter_by(email=email.data).first()
        if user is None:
            raise ValidationError("There is no account with this email.")


class ResetPasswordForm(FlaskForm):
    password = PasswordField('Password', validators=[InputRequired(), Length(min=4, max=200)])
    confirm_password = PasswordField('Confirm Password', validators=[InputRequired(), Length(min=2, max=200), EqualTo('password')])
    submit = SubmitField('Reset Password')

Would highly appreciate anyone's help here

Thank you!

I believe my issue is here in my reset_token function as it is supposed to commits the updated password tot he db and then redirects the user to the sign in page but it is not doing so
