## Highlights

### Regression with workers in Redis Event Bus

This release fixes a critical bug introduced in 2.17.0.

**What**

Not await `bullWorker_.run()` in event-bus-redis `onApplicationStart`

**Why**

`bullWorker_.run()` is designed to return only when the worker is closed (https://github.com/taskforcesh/bullmq/issues/2128). This bug had flown under the radar until we started awaiting all modules `onApplicationStart` [here](https://github.com/medusajs/medusa/pull/15786). The effect is that when running in worker mode, application startup hangs indefinitely. It does not happen in server mode because `bullWorker_` only exists in worker mode.
