Unclear error message notification for "creating timeserie" clause

While I am trying to create a time series whose sensor name is "RANDOM/foo:BYTE", the create timeseries clause failed, because we do not support the characters of "/" and ":" in a path.

However, I can not get the above info, the error message (on the client side) just says:

Meet error while parsing SQL: Statement format is not right: parsing error,statement: CREATE TIMESERIES root.mi.d1.RANDOM_foo:BYTE WITH DATATYPE=INT32, ENCODING=RLE.

While on the server side, you can find the error info: 

Caused by: org.apache.iotdb.db.sql.parse.ParseException: line 1:39 character ':' not supported here
