IpCamera Discovery error

Running the ipCamera discovery features provides the following error:

17:17:08.875 [ERROR] [internal.DiscoveryServiceRegistryImpl] - Cannot trigger scan for thing types '[ipcamera:foscam, ipcamera:onvif, ipcamera:hikvision, ipcamera:amcrest, ipcamera:instar, ipcamera:dahua, ipcamera:generic, ipcamera:doorbird]' on 'IpCameraDiscoveryService'!
