may now fail if this fallback protocol is not specified. Make sure your scrape
endpoints respond with one of the supported Content-type headers:
- `application/vnd.google.protobuf;proto=io.prometheus.client.MetricFamily;encoding=delimited`
- `text/plain;version=0.0.4`
- `text/plain;version=1.0.0`
- `application/openmetrics-text;version=0.0.1`
- `application/openmetrics-text;version=1.0.0`
