Prometheus Metrics Server returns 500 (Internal Server Error) when a Remote Process Group is used. The error message:
{quote}{{java.lang.IllegalArgumentException: Incorrect number of labels.}}
{{at io.prometheus.client.SimpleCollector.labels(SimpleCollector.java:64)}}
{{at org.apache.nifi.reporting.prometheus.api.PrometheusMetricsUtil.createNifiMetrics(PrometheusMetricsUtil.java:408)}}
{{at org.apache.nifi.reporting.prometheus.PrometheusServer$MetricsServlet.doGet(PrometheusServer.java:74)}}
{quote}
Just because the labels number of `AVERAGE_LINEAGE_DURATION` is unmatch.
