Error message

config is already enabled/disabled

What it means

Sentinel error ErrAlreadyEnabledOrDisabled returned by Manager.SetPluginEnabled when the requested state change is a no-op: the plugin conf is already in the requested enabled/disabled state. It is a generic guard used by the API handlers at api/plugin.go:140 and api/plugin.go:198 to answer HTTP 400 instead of 500.

Solutions

1. Check current plugin state before calling SetPluginEnabled and skip redundant calls
2. In the API client, treat this sentinel (errors.Is / == comparison) as an idempotent success rather than a failure
3. Return 200/304-style response in the handler when the desired state already holds
