          I prioritized as minor because this bug does not prevent users from logging in, after which functionality does not seem to be impacted.

          I'm running into this issue for Webhook notifications from Bitbucket. Any ideas how to get around this our why is this happen all of the sudden?

          Root cause for one of our customers was upgrade of the slack plugin - v2.0.0 caused the issue.

          (Whether it is the slack plugin or some weird interaction has not been diagnosed yet).

          Rolling back to 1.8.1 resolved the issue.

          I had the same issue. In the Configure System -> Slack Webhook Settings -> Outgoing Webhook URL Endpoint set a name for the webhook, eg.: slackwebhook. This solves the issue for me.

          Running Jenkins ver. 1.653 and did a rollback of Slack plugin to 1.8.1 - now Jenkins is working again.

          Plugin broken or Jenkins Core?

          Obviously that after manually removing the Slack plugin the option is missing from the configuration. Clearly the plugin is broken badly and the v2.0.0 version must be removed ASAP, as it will cause downtimes.

          Same for me with Jenkins 1.653 as well as 1.642. After disabling the Slack plugin everything is fine again.

          Also I wasn't able to start jobs because of a stack trace from the Slack plugin:

          This plugin seems to be heavily broken.

          Concur that this is critical. It breaks our ability to manage Jenkins with chef because it makes Jenkins appear to be 'down' when it should be and is up.

          Do we have a timeline for when this will be released to LTS?

          Thank you Bartosz, your suggestion works as a quick workaround.

          Placing this script console script in your $JENKINS_HOME/init.groovy.d directory is a workaround.

          https://github.com/samrocketman/jenkins-script-console-scripts/blob/master/disable-slack-webhooks.groovy

          It will permanently disable it. Restart your Jenkins instance for the change to take effect. Until a more permanent fix can be in place.

          I reproduced the issue and thoroughly documented it (including a workaround).

          Moved this to the slack-plugin issues and assigned to Kurt. Closing this issue in favor of issue 191 in GitHub. Please follow up with communication there.
