@GuillaumeDesforges Do you have logs showing the tap errors and exits 0? I'm surprised that's happening

@GuillaumeDesforges I'm closing this PR for now. Please open it again if you want to talk about it

One can find that logging is the only default handler in the backoff lib

See

Right, but the tap should still get the error raised by backoff, catch it here and then exit non-zero. I'm assuming you are seeing different behavior though?
