I am using orientdb 2.0.7
I cannot create lightweight edges in the console
I executed
alter database custom useLightweightEdges=true
If I try to create a lightweight edge labeled "knows" I get the following
error:
Error: com.orientechnologies.orient.core.sql.OCommandSQLParsingException:
Error on parsing command at position #0: Class 'KNOWS' was not found
I am able to create lightweight edges using gremlin.

now go to gremlin console!

there are closed issues on github so I figured I'd ask here first in case
I'm doing something wrong.
