The task result is discarded by Celery (`ignore_result`), so a failing field left no trace beyond a stale entry in `/monitoring/timestamps`. * log the exception with its traceback, as already done for per-item failures in the other Celery tasks * cover the error path with a test This is a prerequisite to enabling the weekly `replace-identified-by` schedule, which would otherwise lose its errors.

The single caller rewrites each log while iterating, so draining the scroll before processing is deliberate. Left unexplained, the `list()` reads as a superfluous cast and invites removal. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Record why the scan is both sorted and materialized: * the order keeps the `not_found` report reproducible, as it holds the access point of the first document seen for a given identifier * `preserve_order` is inseparable from the sort, the scan helper overwrites `sort` with `_doc` without it * the results are materialized because the loop writes to the scanned index Measured on 300k documents, dropping the sort saves about 1.5s, against a loop dominated by MEF requests and reindexing.

WalkthroughThe change adds traceback logging for exceptions in Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change makes failed replacements visible in logs, but the added test does not confirm that traceback details are preserved, so a bounded observability regression could go unnoticed; the PR is mergeable with explicit owner follow-up to strengthen the assertion. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Assert that the log record contains traceback information.
caplog.record_tuples checks only the logger name, level, and message. The test passes even if logger.exception is replaced with a log call that omits exc_info. Inspect the matching LogRecord and assert that record.exc_info contains the expected exception.
Proposed test assertion
- assert caplog.record_tuples[-1] == ("invenio", 40, "replace_identified_by contribution")
+ record = next(
+ record for record in caplog.records
+ if record.getMessage() == "replace_identified_by contribution"
+ )
+ assert record.exc_info is not None
+ assert record.exc_info[0] is Exception
+ assert str(record.exc_info[1]) == "MEF server is down"The PR objective requires this test to verify the full exception traceback, not only the log message.

enabled: Trueon the weeklycelery.replace-identified-byschedule.docs(operation_logs)anddocs(entities): two deliberate patternsBoth changes are comments only, no behaviour change. They record why
list(scan())is intentional in these two places, which is not obviousand was worth a fair amount of digging:
OperationLogsSearch.get_logs_by_record_pid— the caller rewrites eachlog while iterating, so the scroll is drained first.
ReplaceIdentifiedBy.run— the sort keeps thenot_foundreportreproducible, and
preserve_orderis inseparable from it (the scanhelper overwrites
sortwith_docwithout it).On the second one, dropping the sort was measured on a local ES 7.10.2
with an 8-shard index: about 1.5s saved on 300k documents, against a loop
that spends hours on MEF requests and reindexing. Not worth the change,
worth the comment.
