Description

Hey,

When trying to upgrade our Kafka streams client to 2.4.0 (from 2.3.1) we encountered the following exception: 

java.lang.IllegalArgumentException: Number of partitions must be at least 1.

It's important to notice that the exact same code works just fine at 2.3.1.

 

I have created a "toy" example which reproduces this exception:

and I would love to get some insight regarding why its happening / ways to get around it

 

Thanks
