⚠️ Potential issue | 🟡 Minor

🧩 Analysis chain

Verify that the logger object supports all aliased methods.

The module-level aliases for synchronous logging methods look correct. However, since logger is imported from the external lfx.log.logger module, ensure that it exposes all the standard logging methods being aliased here.

🏁 Script executed:

#!/bin/bash
# Description: Verify logger object has the expected methods by checking lfx library usage

# Search for usage of logger.info, logger.debug, etc. to confirm these methods exist
rg -n --type=py -C2 'logger\.(info|debug|warning|error|critical|exception)\(' | head -30

structlog BoundLogger async methods support aerror ainfo

💡 Result:

Yes — structlog's BoundLogger provides async-prefixed methods (ainfo, aerror, adebug, awarning, alog, etc.). These were added in v23.1.0 (you can await log.ainfo(...)). The older AsyncBoundLogger wrapper exists but is deprecated in favor of the a-prefixed methods. [1][2]

Sources:

  • structlog API docs (async variants added, usage example). [1]
  • structlog.stdlib module docs (AsyncBoundLogger deprecation / details). [2]

Sort the __all__ list alphabetically to fix Ruff RUF022 violation.

The logger methods are correctly aliased—structlog's BoundLogger supports all requested sync methods (info, debug, warning, error, critical, exception) and async methods (ainfo, aerror, adebug, awarning, acritical, aexception) since v23.1.0. However, the __all__ list at lines 19-34 is not sorted alphabetically, causing the Ruff linter to fail. Reorder the list alphabetically: acritical, adebug, aerror, aexception, ainfo, awarning, configure, critical, debug, error, exception, info, logger, warning.

In src/backend/base/langflow/logging/logger.py around lines 3-34, the __all__
export list is not alphabetized and triggers Ruff RUF022; reorder the entries in
the __all__ list to be alphabetically sorted as: acritical, adebug, aerror,
aexception, ainfo, awarning, configure, critical, debug, error, exception, info,
logger, warning so the linter passes.


# Expose async logger methods at module level
aerror = logger.aerror
ainfo = logger.ainfo
adebug = logger.adebug
awarning = logger.awarning
acritical = logger.acritical
aexception = logger.aexception
