Importing library content fails with error "com.spotfire.ws.library.StorageException, ILLEGAL_ARGUMENT, The item cannot be parent of itself"

It is common to export dashboards from Development and then import them to the Production Spotfire environment which in Spotfire terms is called Library export/import.

Library import can fail when trying to perform an import in the same folder structure hierarchy as it is exported.

Consider this hierarchy in the Spotfire library-
  /
    Folder1
       Folder2 
           Mydxp

Assume this folder structure and dxp exists in both Dev and Production environments and now you would want to export the updated Mydxp from Dev and import it in a Production Spotfire environment.

For this you would export Folder1 from the Spotfire Library say 'Test1.zip'.The export would contain Folder1-Folder2-Mydxp.

The next step is to import Test1.zip in the Production Spotfire environment. As the folder hierarchy already exists in Production ,the import needs to be performed using the 'Replace existing item' option .The import is initiated and the destination folder to import to is set as 'Folder1'.

Spotfire will start importing and then fail with an error -

com.spotfire.ws.library.StorageException: ILLEGAL_ARGUMENT, The item cannot be parent of itself

This error will be logged in the {Spotfireserverinstall}/tomcat/logs/impex.log
