Undue 405 error with POST request

See original GitHub issue

Describe the bug

Sanic gives a HTTP 405 on POST request while it should give a HTTP 200. Problem does not happen with previous Sanic versions.

Code snippet

Example app:

from sanic import Sanic
from sanic.response import text

app = Sanic("test")

@app.route("/test/", methods=["POST"])
def do_post(request):
    return text("from post")

@app.route("/test/<foo>", methods=["GET"])
def do_get(request, foo):
    return text(foo)

app.run()

Client test:

user/Downloads : python3
Python 3.9.4 (v3.9.4:1f2e3088f3, Apr  4 2021, 12:19:19) 
[Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from requests import get, post
>>> (post("http://localhost:8000/test/"), get("http://localhost:8000/test/ok"))

Result with Sanic 21.12.1:

(<Response [405]>, <Response [200]>) Result with Sanic 20.12.3:

(<Response [200]>, <Response [200]>)

Expected behavior

Sanic should give an HTTP 200 to the POST request.

Environment (please complete the following information):

OS: MacOS
