Hello, its my first post here.
Mattermost 5.7.0, internal IP, no domain.
Even though integration with jenkins (same LAN, docker container) does work, i cant set icon/avatar for notifications. I set up icon field in jenkins global settings with jenkins PNG icon. Test message changed from icon=null to icon=’’. I tried to set it manually in pipleline …
mattermostSend icon: 'https://jenkins.io/images/logos/jenkins/256.png', color: "danger", message: "Some error"
Doesnt work either. Notifications comes with first user name (admin) and icon.
