The maps for the specified data objects cannot be combined into the target map file.

Explanation

There is a call to the public static void combineMaps(String datastore, String targetMapName, String[] source, boolean updateScriptDefs) method from ObjectMap class. The source array that represents the source data objects contains the name of a file that does not exist or is not a map file or a script definition file. The sourceName source data object must be either a map files or script definition files. Specifying any other type of file is not valid and causes an error.

User response

Make sure that the sourceName source data object is valid, and try to combine the data objects again.
