Hi Протченко, Yes you cannot get a Map argument from ParameterTool directly. ParameterTool fetches and stores data in the form of string so it's not feasible to support any types of configuration values which may be set by users.
A workaround is to convert the map to a string in head and parse it later in the main method.
