Errors don't show up in Slack. Here are a few things to try out.

  • Make sure that the Slack app is installed on the log as described above.
  • Only new errors are sent to Slack. A new error has a severity of Error or Fatal and is marked with a yellow star on the search tab. We only send new errors to help you stay out of Slack's API limits. If sending all errors, you could quickly end up in a scenario where the same error is sent multiple times and more important errors get ignored by Slack.
  • Make sure that your token is still valid. The only way to resolve an issue where the token is no longer valid is to re-install the Slack app.
