Thanks for your contribution.

So you were mentioning in the issue that it wasn't working as intended ? Were you able to fix that ?

I wonder if we should, somehow, test that. Maybe install this in a procrastinate_demo project ? Do you have an opinion ? (I'm not saying you have to do this on the PR (but you may), just asking. Your PR may should get merged at some point, even without that)

(I think we're using python elsewhere, rather than py)

Hm, I've tried your code and it hasn't worked on the demo so far. I'll try to share a complete traceback later, but has it been working for you ?

Yes, it has on a bigger project. Did you try the minimal config or the one from the structlog docs?

I tried the one from your PR, and tried to put it as-is in the sync demo.
