[Python] Custom log level not working with structlog

I am working with python custom log - TRACE is custom log level in below code.

With default logger, its working fine

But when I change it for structlog it is giving error.

structlog not able to identify TRACE in below code.

It seems that structlog doesn't support custom log levels ?

Already tried workaround mentioned https://github.com/hynek/structlog/issues/47

i.e

structlog.stdlib.TRACE = TRACE = 5
structlog.stdlib._NAME_TO_LEVEL['trace'] = TRACE


But it is not working

TRACE = 19


logging.addLevelName(TRACE, "TRACE")

logging.basicConfig(
level=os.environ.get("LOGLEVEL", "TRACE"),
format=os.environ.get("LOGFORMAT", '%(levelname)-8s= %(asctime)-15s = %(message)s'))



structlog.configure(
processors=[
structlog.stdlib.filter_by_level,
structlog.stdlib.add_logger_name,
structlog.stdlib.add_log_level,
structlog.stdlib.PositionalArgumentsFormatter(),
structlog.processors.StackInfoRenderer(),
structlog.processors.format_exc_info,
structlog.processors.UnicodeDecoder(),
structlog.stdlib.render_to_log_kwargs,
],
context_class=dict,
logger_factory=structlog.stdlib.LoggerFactory(),
wrapper_class=structlog.stdlib.BoundLogger,
cache_logger_on_first_use=True,
)




#LOG = logging.getLogger() ->> Working fine
LOG = structlog.getLogger()



LOG.log(TRACE, "hello") ->> error on this line
LOG.info("testing")
