Hi guys, I’m facing an issue trying to connect to kafka using the broadway_kafka connector, I need to pass a user and pass but I’m getting an error that it couldn’t join the given group, looking the output I see the arguments are not being taken as expected, looks like the password position is being held as the callback, even when I pass the :plain key in config:

Output config on start:

mfargs: {:brod_client, :start_link,
   [
     [{"xxxx.aws.confluent.cloud", 9092}],
     HubspotWorkers.HubspotDuplicaetDomainsWorker.Broadway.Producer_0.Client,
     [
       sasl: {:plain, "user",
        #Function<11.44977799/0 in :brod_utils.init_sasl_opt/1>}
     ]
   ]},
  restart_type: {:permanent, 10},
  shutdown: 5000,
  child_type: :worker

Output error:

Leaving group, reason: :shutdown

My config:

{BroadwayKafka.Producer,
           [
             client_config: [sasl: {:plain, "user", "password"}],
             hosts: "xxxxx.aws.confluent.cloud:9092",
             group_id: "xxxx_1",
             topics: ["xxxx.events.json"]
           ]},

What is wrong? Am using broadway_kafka 0.4
