BatchApexErrorEvent can be subscribed in LWC as well. For this, we have to import the required functions from lightning/empApi module and the channel name is '/event/BatchApexErrorEvent'. In this example, we have subscribed to the  BatchApexErrorEvent using LWC and showing a toast error message on receiving the error.

BatchApexErrorEvent  is a built in event which is triggered for unhandled exception in batch class. In order to raise platform events from batch apex, we need to implement Database.RaisesPlatformEvents interface. We can subscribe to BatchApexErrorEvents using platform event type triggered flow.
