a Result indicating whether the map was successfully saved. The result will be a failure with type:

The portal to save the map to.
The folder in which to save the map. If null, it will be added to the user's root folder.

A Boolean value indicating whether the map should be saved to the supported web map version that the API supports (see system requirements). This may cause data loss as unknown data is not saved. If true, unknown data will be removed and the map will be saved. If false, the asynchronous operation will fail if the map contains unknown data that will not be saved. This flag can be used to provide a warning to users that some map data may be lost when the map is saved.
