Describe the issue:
First, I create a monitor and try to get notified via the trigger’s action, but it says the channel doesn’t exist.
but i have 1 channel.
So I tried recreating the channel, but it still says it doesn’t exist.

Relevant Logs or Screenshots:

Can confirm the issue, running in Kubernetes environment using the latest available versions from the helm charts (OS 2.14.0, OSD 2.14.0). Also using the slack notification channel. Also tried to create an SMTP channel, this has the same issues.

The logs are pretty “dry”, no warnings, errors or stack traces in OS or OSD logs. I do however see a failed HTTP request (400 error) in the browser console to the GET <url>/api/notifications/get_configs?from_index=0&max_items=5000&sort_field=name&sort_order=asc with the following reply:

{"statusCode":400,"error":"Bad Request","message":"[request query.config_type]: expected at least one defined value but got [undefined]"}

Edit: in Index management, when configuring notifications for index actions, the notification channel is available and visible. Seems to be a problem with the alerting plugin?

I’ve submitted a bug report in Github: [BUG] Dashboard Alerting plugins fails to retrieve available notification channels · Issue #961 · opensearch-project/alerting-dashboards-plugin · GitHub

Edit: it seems this is a bug introduced in v2.14.0 , which should be fixed when [Backport 2.x] Refactored code to account for notifications server features API change by opensearch-trigger-bot[bot] · Pull Request #955 · opensearch-project/alerting-dashboards-plugin · GitHub is merged.
