Environment

Ubuntu 22.04.5 LTS, x86_64, one-zone loopback observer.

Steps to reproduce

As root@sys on a disposable cluster, use an overlength synthetic password (139 bytes in the authoritative run):

CREATE STANDBY TENANT edbf_standby
  LOG_RESTORE_SOURCE=
  'SERVICE=127.0.0.1:1 USER=edbf@edbf PASSWORD=EDBF_LOG_RESTORE_PASSWORD_SENTINEL_20260901AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';

The statement returns error 1210 during local argument validation. Inspect the new run's observer and rootservice logs; both complete authoritative files are bundled as artifacts/observer.log and artifacts/rootservice.log:

WDIAG ... parse restore source service password failed(
  name=password,
  value=EDBF_LOG_RESTORE_PASSWORD_SENTINEL_20260901AAAAAAAA...,
  ret=...)

The sink is src/share/backup/ob_log_restore_config.cpp:435. A pre-trigger log scan was negative; the post-trigger scan found the complete unique marker. A tenant-count query confirmed that edbf_standby was not created.

✔️ Expected Behavior

LOG_RESTORE_SOURCE validation errors should report the invalid field name, constraint, and safe length metadata without printing the password value.

❌ Actual Behavior

The parser's error branch writes the complete rejected password to a warning log. The parser fails before tenant scheduling, no network connection occurs, and the observer stays healthy.
