92002: LiveObjects operation on a deleted 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: <id>.
