The node name has one or more characters that is not supported on server versions earlier than 7.1.1. The character is the '@' sign.
The server skips the node name and operation continues.
Check if the node name has the '@' (at sign) character. Node names with the '@' character are supported on server versions 7.1.1 and newer. Reissue the command specifying a different node name, or, rename the node name and reissue the command.
