Description
Hi,
Using the code sample from https://github.com/open-telemetry/opentelemetry-python/blob/v1.12.0rc1/exporter/opentelemetry-exporter-prometheus/src/opentelemetry/exporter/prometheus/__init__.py
from prometheus_client import start_http_server
from opentelemetry.exporter.prometheus import PrometheusMetricReader
from opentelemetry.metrics import get_meter_provider, set_meter_provider
from opentelemetry.sdk.metrics import MeterProvider
import random
start_http_server(port=8000, addr="localhost")
prefix = "MyAppPrefix"
reader = PrometheusMetricReader(prefix)
set_meter_provider(MeterProvider(metric_readers=[reader]))
meter = get_meter_provider().get_meter("myapp", "0.1.2")
counter = meter.create_counter(
"requests",
"requests",
"number of requests",
)
labels = {"environment": "staging"}
counter.add(25, labels)
when accessing http://localhost:8000 and exception is thrown

This also happens when I try an up_down_counter
gauge = meter.create_up_down_counter(
'requests_for_endpoints_ms',
'millis',
'Requests for endpoints in milliseconds'
)
res = random.choice(results)
gauge.add(random.randint(10, 40), {'endpoint': res['endpoint']})
