How are run-time errors reported?

Each notification configuration might return an error generated at runtime. Examples of this errors are:

• Insufficient privileges in JIRA - for instance, retrieval of related users or projects. 
• Errors during template evaluation. Some fields might be missing or in wrong format
• Bad credentials for Email or Slack. 
• IO related problems

These errors are reported to user on the list of Raley notifications just below the names of respective notification configuration. When you fix it, assuming that the fix was correct, the error message will disappear next time the notification configuration is successfully run.
