apologies if not: is this question directed at me?

to anyone who knows the answer:upside_down_face:

this error basically means you tried to feed an event in a pipeline while it's still processing the previous one

in general, the right way to solve this is to insert a relieve stage right after observe, to cover this scenario

@U053XQP4S unfortunately in my case no matter where I place the relieve it does not help

I will try to make a minimal example

I was wrong, it works
