DMS task status not updated to failed.

Hello,

We are using AWS DMS and we run into an issue.

We are using DMS engine version 3.4.6 with Oracle 11.2.0.4 as source and PostgreSQL 13.3 destination.

At some point during the on-going replication the table public.awsdms_apply_exceptions is dropped.

Important precision: this table drop is was a mistake in our side.

This status is correctly reported in the task's logs at 2022-07-18T10:09:51 (see below). But the tasks status is not updated to failed or another status than Load complete, replication ongoing in the DMS web dashboard whereas the log reports:

2022-07-18T12:10:19.000+02:00	2022-07-18T10:10:19 [TASK_MANAGER ]I: Task - PX242JWPJG2JGAF43IIYQOJGLRH2JIPSGHIMGWQ is in STOPPED state, updating starting status to AR_NOT_APPLICABLE (repository.c:5102)

The tasks should be updated to failed.

Here is an extract of the end of the task log:
