We have some alerts setup using the Slack Webhook Alert Add-On, however after some testing, we have found that only Admins have the ability to create alerts that successfully use this alert action. I setup the permissions on the alert action so that the role of my non-admin users(default power role) has write access, but this still did not allow the alerts to fire. The error that is displayed in the logs is:
INFO sendmodalert - action=slack_webhook_alert - Alert action script completed in duration=8042 ms with exit code=5 WARN sendmodalert - action=slack_webhook_alert - Alert action script returned error code=5
Any help in figuring out what permissions are needed in order to allow my users to create and manage their own alerts without providing admin privileges would be very appreciated.
