Duplicate route names error

[m-aliansari]

Describe the bug The getting started example in the sanic-openapi docs does not appear to be working with the latest sanic version. It's giving duplicate route names error. I used the code in this URL https://sanic-openapi.readthedocs.io/en/stable/sanic_openapi2/index.html. Also there is a simple error that sanic doesn't allow spaces in the app name, so the line app = Sanic("Hello world") should be changed to app = Sanic("HelloWorld"). I am attaching the error below.

Screenshots

To Reproduce

from sanic import Sanic
from sanic.response import json
from sanic_openapi import openapi2_blueprint

app = Sanic("HelloWorld")
app.blueprint(openapi2_blueprint)


@app.route("/")
async def test(request):
    return json({"hello": "world"})


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)
