Upon upgrading to OH-4.3.0, I am seeing this error at startup or anytime the bond bridge is disabled and re-enabled. The issue appears to be a race condition where the discovery service attempts to start calling request() before bridgeHandler.getBridgeIpAddress() can provide the IP address of the bridge. By catching the IllegalArgumentException , the service will continue and is able to discover devices in subsequent scans.
