I've followed an example how to set pipelines project using this video: https://www.youtube.com/watch?v=0-FugzVYJQU . Bitbucket webhook is created, and it notifies jenkins, however jenkins does nothing after receiving it. I see the following lines in the log:

May 26, 2020 2:02:40 PM FINE com.atlassian.bitbucket.jenkins.internal.trigger.BitbucketWebhookEndpoint
Payload: com.atlassian.bitbucket.jenkins.internal.trigger.RefsChangedWebhookEvent@3a67ec4d
May 26, 2020 2:02:40 PM FINE com.atlassian.bitbucket.jenkins.internal.trigger.BitbucketWebhookConsumer
{{Received refs changed event from repo: PROJ/acs }}

Triggering project » ACS

Pipeline is set to build from Jenkinsfile and from any branch (branch selector set to: **). Build trigger is set to: Bitbucket Server trigger build after push
