java.lang.IllegalArgumentException: Topic name can only have ASCII alphanumerics, '.', '_' and '-', but was: ' consumer-in-0'

Question

In my application.yml, I have this code :

spring.cloud.stream:
  function:
    definition: producer; processor; consumer
  bindings:
    producer-out-0:
      destination: numbers
    processor-in-0:
      destination: numbers
    processor-out-0:
      destination: squares
    consumer-in-0:
      destination: squares

But I am getting this error: Topic name can only have ASCII alphanumerics, '.', '_' and '-', but was: ' consumer-in-0'. Can someone see what is the issue?

I founded the error in this line there should be no spaces after semi-colons:

definition: producer; processor; consumer

It should be like:

definition: producer;processor;consumer
