Class: ContainerLockedError

Defined in: packages/core/src/errors/ContainerErrors.ts:51

Raised when application code tries to register a binding through the App facade after Application.boot() has completed.

The container is process-global and shared across every concurrent request, so mutating it at request time would leak state between requests. Register bindings at boot — in the bootstrap App.bind() callback, a ServiceProvider, the app/services convention, or top-of-module code — and use a scoped binding for anything that must be per-request.
