Method not implemented.

Error message

Method not implemented.

What it means

hideGroup on the AppSettingBridge is a stub: Rocket.Chat logs the call and unconditionally throws 'Method not implemented.'. The apps-engine API surface exposes the operation, but the server never implemented hiding a settings group on behalf of an app, so every call fails regardless of arguments.

Solutions

1. Remove the hideGroup call: the operation is unsupported server-side; control section visibility in the app's own settings declaration instead.
2. If the capability is required, track/file the upstream feature request against the apps-engine bridge.
3. For 'hide my own settings after setup', store a configured flag in app storage and stop rendering the section in your UI logic instead of hiding it.

If the call sits on a shared path, catch 'Method not implemented.' and continue — it is deterministic and has no recoverable state.

When it happens

Trigger: App calls the settings modification API to hide a settings group by name (hideGroup). Always throws; no argument makes it succeed.

Common situations: Apps copied from samples or older code that call hide APIs; apps wanting to hide their own settings group after initial setup.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
