[s-celles]

Hello,

using AMQPClient
login, password = "guest", "guest"
port = AMQPClient.AMQP_DEFAULT_PORT
auth_params = Dict("MECHANISM"=>"AMQPLAIN", "LOGIN"=>login, "PASSWORD"=>password)
conn = connection(;virtualhost="/", host="localhost", port=port, auth_params=auth_params)

raises the following error
