How to reproduce
⚠️ This is the most important part of the report⚠️
Sorry... i have absolutely no idea... Ive only observed it today and only in development where Im stopping and starting workers a lot.
I launch 50 message:consume workers in development, and 3-5 of them each time fail with this, and then auto-restart with supervisor)
As its just a warning, Im hoping its a quick obvious fix for someone closer to the code
Warning: Undefined array key 0
