Fail import data from another environment during installation

I'm trying to install new confluence server and take the data from another environment. The backup zip from another environment copied to

/restore before first starting of the server.
The process fails during the import with the following exception:

INFO: Initializing Spring root WebApplicationContext
Exception in thread "Importing data task" java.lang.NullPointerException
at com.atlassian.confluence.importexport.actions.ImportLongRunningTask.runInternal(ImportLongRunningTask.java:50)
at com.atlassian.confluence.util.longrunning.ConfluenceAbstractLongRunningTask.run(ConfluenceAbstractLongRunningTask.java:21)
at java.lang.Thread.run(Thread.java:619)

log.info("Beginning import by user " + context.getCurrentUser().getName());

I think the problem is missed user during installation. The expression context.getCurrentUser() returns null.
Can you fix it please?
