    java.lang.NullPointerException
  2. 0

    When I access the jenkins main page for my project (which was functional as of Friday) I hit a null pointer exception that looks something like this: java.lang.NullPointerException at jenkins.plugins.slack.webhook.WebhookEndpoint.getUrlName(WebhookEndpoint.java:51) at jenkins.model.Jenkins.getUnprotectedRootActions(Jenkins.java:4342) at
