I would like to log correlation id in every log messages via Loguru. I tried to use logger.contextualize(correlation_id=id). It works in the parent thread but not the child thread. How do I get the correlation id to be logged in the child thread as well?

logger.remove(0)
logger.add(sys.stderr, format="{time:MMMM D, YYYY HH:mm:ss} | {level} | {message} | {extra}")

class Client:
  def get_data(self):
    logger.info("get_data")

class ProcessThread(threading.Thread):
  def __init__(self, client):
    threading.Thread.__init__(self)
    self.client = client
    
  def run(self):    
    logger.info("inside child thread")
    self.client.get_data()


def test(id):
  with logger.contextualize(correlation_id=id):
    process_thread = ProcessThread(Client())
    logger.info("inside parent thread")
    process_thread.start()

test('101')

Current output is

January 17, 2023 21:14:08 | INFO | inside parent thread | {'correlation_id': '101'}

January 17, 2023 21:14:08 | INFO | inside child thread | {}

January 17, 2023 21:14:08 | INFO | get_data | {}

But I want it to be

January 17, 2023 21:14:08 | INFO | inside parent thread | {'correlation_id': '101'}

January 17, 2023 21:14:08 | INFO | inside child thread | {'correlation_id': '101'}

January 17, 2023 21:14:08 | INFO | get_data | {'correlation_id': '101'}

Any insights?

You are not providing the contextual information inside get_data() and run().

Just do with logger.contextualize(correlation_id=id): for both of them and it should work.

logger.contextualize loses the context when you go out of with
