create_database_user call results in JSON parse error

[flightjumpr]

The following example is given in the documentation

database = 'site_development'
new_username = 'foo'
new_password = 'bar'
permission = :write

###with all permissions
influxdb.create_database_user(database, new_username, new_password)

This amounts to the following for me

JSON::ParserError: A JSON text must at least contain two octets!

The execute block in create_database_user seems to be returning an "" source which the parse method is trying to execute upon.
