Steps to Reproduce
NOTE: # ( Please be as specific as possible. )
[TIP]: # ( Link a sample application that demonstrates the issue. )

Start a Sanic app with a class based controller and newrelic instrumentation. Curl the URL, you see the warning. Same CURL without Newrelic has no warning.

from sanic import Sanic
from sanic.response import text
from sanic.views import HTTPMethodView

class TestController(HTTPMethodView):
    async def get(self, request):
        return text("hi")

app = Sanic("testapp")
app.add_route(TestController.as_view(), "/test")

Your Environment
[TIP]: # ( Include as many relevant details about your environment as possible including the running version of New Relic software and any relevant configurations. )

newrelic 8.0.0.179
sanic 21.6.2
