Prometheus plugin endpoint showing blank page

See original GitHub issue

Below is my jenkins environment.

Jenkins - 2.263.1(LTS) deployed through tomcat.
Prometheus metrics plugin - 2.0.8

http://jenkins-server/jenkins/prometheus just shows the blank page on my browsers.

My prometheus.yml

  - job_name: 'jenkins'
    metrics_path: '/jenkins/prometheus'
    scheme: http
    static_configs:
    - targets: ['jenkins-server:80']

Even tried with authentication, however still blank page shown.

basic_auth:
  username: domain-user
  password: 98qw37asdkdsjfeiq1dedsewe

Jenkins system log section below message shown.

A thread (prometheus_async_worker thread/77119) died unexpectedly due to an uncaught exception, this may leave your Jenkins in a bad way and is usually indicative of a bug in the code.
java.lang.NullPointerException

Refered this issue - https://github.com/jenkinsci/prometheus-plugin/issues/82 however it is closed, can’t find the workaround in that.

There are a handful of similar tickets and I believe some root causes have been resolved and merged but we are waiting for the next release. Any updates on when this will be released? A lot of us are waiting and unable to use the plugin due to the bugs.

I did that many times, however still experiencing the same issue.
