This error makes no sense because

From our Gemfile.lock:

sidekiq-pro (5.5.2)
  sidekiq (>= 6.5.0)

redis (5.0.5)
  redis-client (>= 0.9.0)

CodePudding user response：

The signature on that method includes a named argument timeout which defaults to 0. Ruby will accept a hash at end of the list of arguments, but not an Integer or similar.

I suspect config[:fetch_timeout] is nil, therefore the value of 1 is being passed, thus the error message.

Maybe see where config[:fetch_timeout] is being set and make sure it contains a hash value like { timeout: 1 }.

If you want to get your head around why you get that particular error message, consider this method:

def foo(a, test: 1)
  puts test
end

Calling foo(1, 1) will trigger a (wrong number of arguments (given 2, expected 1)) error, whereas foo(1, test: 2) will work.
