Hi, @muthuaravind

It seams like you use the string IDs feature of the backend janus-gateway which is not supported by Janus-cloud. please check the configuration file of the videoroom pluagin of the backend janus-gateway, which looks like below:

general: {
    #admin_key = "supersecret"      # If set, rooms can be created via API only
                                    # if this key is provided in the request
    #lock_rtp_forward = true        # Whether the admin_key above should be
                                    # enforced for RTP forwarding requests too
    #events = false                 # Whether events should be sent to event
                                    # handlers (default=true)

    # By default, integers are used as a unique ID for both rooms and participants.
    # In case you want to use strings instead (e.g., a UUID), set string_ids to true.
    #string_ids = false            ********************** important: must set to false
}
