# 92002: LiveObjects operation on a deleted object Identifier: `operation_on_tombstone_object` An operation could not be applied because the target LiveObject had already been deleted. A deleted object is retained only as a marker, or tombstone, and can no longer be modified. ## What you should do Stop applying operations to the deleted object. Once an object is deleted it can no longer be modified, so recreate it, or target a different object, if you still need to make the change. ## Why it happens The operation targeted an object that had already been deleted. Ably retains a deleted object only as a marker so the deletion propagates, but it no longer accepts operations. ## What you'll see The error is reported with code 92002 and HTTP status 400. The message is `unable to submit operation on tombstone object: `.
