#10111 fix: Stop emitting null `plugin_exception` and `stream_name` keys for every single log Pull request opened by edgarrmondragon Description Checklist • I have read the contribution guide Was generative AI tooling used to co-author this PR? • Yes (please specify the tool below) Related Issues • Closes #XXXX Summary by Sourcery Adjust structured logging of Singer SDK output to avoid emitting null fields and expose parsed stream metadata and exceptions more cleanly. Bug Fixes: • Stop including null

plugin_exception

and

stream_name

fields on every structured log entry when no value is present. Enhancements: • Capture

stream_name

and plugin exception details as first-class fields on parsed Singer SDK log records and propagate them via logger extras. Tests: • Extend Singer SDK log parsing tests to cover

stream_name

extraction and add coverage for logging structured plugin exceptions through

OutputLogger
