Operations center 2.440.3.7 "Manage Jenkins" page shows "A problem occurred while processing the request"

Issue

I have upgraded my operations center to release 2.440.3.7 and navigating under Manage Jenkins triggers an error in the UI presenting "A problem occurred while processing the request" and an error identifier. In addition, when reviewing the logs, the following exception is listed:

WARNING	h.i.i.InstallUncaughtExceptionHandler#handleException: Caught unhandled exception with ID $SOME_ERROR_IDENTIFIER
org.apache.commons.jelly.JellyTagException: jar:file:/tmp/jenkins/war/WEB-INF/lib/jenkins-core-2.440.3-cb-3.jar!/hudson/model/ManageJenkinsAction/index.jelly:45:57: <st:include> No page found 'message.jelly' for class com.cloudbees.casc.server.BundleLoadFromDiskErrorAdminMonitor
	at org.kohsuke.stapler.jelly.IncludeTag.doTag(IncludeTag.java:149)
    [...]▼

Environment

CloudBees CI on modern cloud platforms - operations center

CloudBees CI on traditional platforms - operations center

Resolution

This is an introduced bug in the release 2.440.3.7 in the Administrative Monitor warnings related to errors in the configured CasC bundles printed under Manage Jenkins and it will be fixed in the upcoming CloudBees CI release.

Workaround

As a workaround while waiting for the release, you can navigate directly in the browser to $OPERATIONS_CENTER_URL/manage/configure and disable the problematic Administrative Monitor called BundleCheckoutErrorAdminMonitor.
