WalkthroughChangesThe pretty console renderer now removes Pretty console logging
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to Pretty console logs can still display service=langflow when an explicit log format is configured, and the regression test may be affected by CI environment variables; these bounded correctness and test-readiness issues should be fixed before merging.

Isolate the default-service test from environment variables.
Clear LANGFLOW_SERVICE_NAME and LANGFLOW_LOG_FORMAT before configure. A CI environment can set either variable. The test can then pass without exercising the default langflow value or the default ConsoleRenderer path.

Apply the filter to every human-readable console branch.
When LANGFLOW_PRETTY_LOGS=true and LANGFLOW_LOG_FORMAT is set, the KeyValueRenderer branch at Lines 1153-1156 runs. This processor is skipped. The output still contains service=langflow.
Add the processor before the if log_format split. Add a regression test for this configuration.
Suggested placement

+ processors.append(_hide_default_service_for_pretty_console)
if log_format:
processors.append(structlog.processors.format_exc_info)

else:
- processors.append(_hide_default_service_for_pretty_console)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The default
service=langflowmetadata adds noise to human-oriented pretty console logs. Hide only that implicit default in pretty output while preserving custom service names and structured log metadata.Fixes #13615
