Mysensors binding items error

So why are you trying to add this?

Bridge mysensors:bridge-eth:gateway [ ipAddress=“127.0.0.1”, tcpPort=5003, sendDelay=200 ] {
/** define things connected to that bridge here */
}

This is a thing, not an item.
Are your mysensors devices discovered on the paperUI?

Can you post the .items file, please?
