I believe you could just use this signal to do this:

https://django-structlog.readthedocs.io/en/latest/api_documentation.html#django_structlog.celery.signals.modify_context_before_task_publish

>>> from django.dispatch import receiver
>>> from django_structlog.celery import signals
>>>
>>> @receiver(signals.modify_context_before_task_publish)
... def receiver_modify_context_before_task_publish(sender, signal, context):
...     if "user_id" in context and context["user_id"]:
...         context["user_id"] = str(context["user_id"])

I created the issue #46 to find a more generic solution. Thank you @fadedDexofan for this proposition.

[jrobichaud]

@fadedDexofan could you show me how to reproduce the problem using the demo project?

[jrobichaud]

This PR finally fixes #51 I noticed while trying to reproduce your problem.

@fadedDexofan in 1.6.2 there is your fix so you might want to upgrade and remove the workaround I gave you.
