GML-2083-TextFile-UnboundError : fix UnboundLocalError in community desc poll during rebuild

[prinskumar-tigergraph]

User description

Return False and log full traceback when communities_have_desc (or embedding check) fails so the wait loop retries instead of crashing the rebuild TaskGroup.

Description

• Return false after polling failures

• Validate polling responses before indexing

• Log tracebacks for diagnostics

⚡ Recommended focus areas for review Type Validation The new response handling validates presence of the expected keys but not that the returned values are booleans. A malformed truthy value such as a non-empty string could cause the wait loop to treat the rebuild as complete instead of retrying. try: res = resp[0]["all_have_desc"] except (IndexError, KeyError, TypeError) as e: logger.error( f"Check Vert Desc unexpected response {resp!r}: {e!r}" ) return False logger.info(res) return res Type Validation The embedding poll result is returned directly after key lookup. Consider explicitly checking that all_have_embedding is a boolean to avoid malformed truthy values prematurely ending the wait loop. try: res = resp[0]["all_have_embedding"] except (IndexError, KeyError, TypeError) as e: logger.error( f"Check embedding rebuilt unexpected response {resp!r}: {e!r}" ) return False logger.info(resp) return res
