Hi,

I juste updated my resource from 1.7.1 to 1.8.0 with concourse 7.11.2 and this conf:

  - name: mattermost-dev
    type: slack-notification
    source:
      disable: false
      insecure: true
      url: https://...
    icon: slack

  put: mattermost-dev
  params:
    username: Concourse
    text_file: output-notif/notification.txt
    text: |
      ##### :heavy_check_mark: :green_book: **OK $BUILD_PIPELINE_NAME** - <$ATC_EXTERNAL_URL/teams/$BUILD_TEAM_NAME/pipelines/$BUILD_PIPELINE_NAME/jobs/$BUILD_JOB_NAME/builds/$BUILD_NAME| $BUILD_JOB_NAME #$BUILD_NAME>
      $TEXT_FILE_CONTENT

And I have this log

I think it's related to #97

I see the below error coming back from the slack API. * The requested URL returned error: 400 Which indicates it failed. Part of the commit was making it fail in situations were it was incorrectly passing before. Have you looked at the older version of the container? Was it also getting a 400 back from the endpoint?

I suspect this has been failing silently until now, and now it's failing loudly.
