Service Operation Failure During Hook Execution

FeathersJS Hook Error Propagation

The goal is to confirm how FeathersJS handles service operation failure when an error is thrown within a lifecycle hook, specifically a 'before' hook.

Constraints and Uncertainty

FeathersJS does not provide automatic transactional rollback across schema modifications; this relies on external tooling.

When an error occurs in a 'before' hook, does the framework guarantee that subsequent 'after' hooks for that specific service operation will not execute?

• Does the error propagate immediately to the caller?
• Is the service state considered partially updated if the error occurs mid-hook execution?
